(BUTLER, P.A.) — Federal authorities are investigating after former President Donald Trump was shot in the ear in an assassination attempt at an election rally in Butler, Pennsylvania, on Saturday.

Blood splattered on Trump’s face as Secret Service agents surrounded him and led him off the stage to a waiting vehicle to whisk him away. Trump is “fine,” a spokesperson said.

The alleged shooter was killed by snipers. One spectator was killed and two were hurt, officials said.

Crooks seen walking around magnetometers before shooting: Sources

Minutes before the shooting, gunman Thomas Matthew Crooks was seen walking around near the magnetometers and people reported him as suspicious, according to law enforcement sources.

Crooks then climbed on top of air conditioning units and pulled himself up to the roof of the building beside those units, sources said.

Once on the roof of that first building, he worked his way toward another taller, adjacent building that gave him the vantage point to fire in Donald Trump’s direction, sources said. He jumped and landed where he wanted to be and slowly made his way to the summit of the sloped building, sources said.

Secret Service agents heard radio traffic about a suspicious person and later heard another radio dispatch about some sort of confrontation with police, sources said.

When bystanders noticed Crooks, an officer climbed up, sources said. Crooks pointed his gun at the officer who fell to the ground, sources said.

What we know about the shooting

As the FBI investigation continues, questions are swirling about how a 20-year-old Pennsylvania man was able to ascend undetected to a roof near a Trump rally, gain a direct line of sight and fire several rounds at the former president. Read more here. 

DHS inspector general opens investigation into Secret Service’s handling of rally

The Department of Homeland Security’s inspector general has opened an investigation into the Secret Service’s handling of the rally.

A new bulletin listed under “ongoing projects” on the DHS Office of Inspector General website said the project objective is to “evaluate the United States Secret Service’s (Secret Service) process for securing former President Trump’s July 13, 2024 campaign event.”

Senators to be briefed Wednesday

Senators will receive an unclassified, all-senator briefing via phone call Wednesday afternoon, according to Senate Majority Leader Chuck Schumer’s office.

The Secret Service, FBI and Department of Justice will address the senators.

The House will also have an unclassified, all-member virtual briefing Wednesday afternoon, multiple sources said.

Authorities detail how they suspect the gunman reached roof; motive still a mystery

Authorities suspect Thomas Matthew Crooks, the man they allege tried to assassinate former President Trump, was able to access the roof by climbing over an air conditioning unit adjacent to the building, sources tell ABC News. Though law enforcement sources say Crooks is believed to have purchased a 5-foot ladder at a Home Depot before the shooting, it does not appear to have been used to climb on the roof and was not found at the scene.

Investigators found a remote transmitter in the suspect’s pocket that may have been intended to set off two suspicious devices found in the suspect’s car and one in his home, according to law enforcement sources.

Devices at both locations were similarly constructed in ammunition containers using components including receivers that appear to have been paired with the remote control found in the suspect’s pocket, sources said.

The receivers in each device were connected to a series of components that investigators say met the “eye test” — having parts present that could have made viable devices, although the functionality of the devices is still being determined. The purpose of the devices is also unknown. Whether they were intended to cause a significant blast effect and hurt people or if they were designed to create smoke, fire and a low-grade blast for a diversion is unclear.

Investigators also found a tactical vest in the suspect’s car, though it is unclear why he did not wear it during the assault on the former president’s rally. Some investigators are wondering whether he anticipated dying in the attack.

The shooter also asked his employer if he could take a day off on Saturday but said he would return to work perhaps as soon as Sunday, the day after this attack, according to law enforcement sources. But thus far, investigators have turned up nothing to suggest that he had any accomplices or other support to carry out his deadly objective.

An examination of his phone, which the FBI has now unlocked, has not turned up any significant information about the suspect’s motives — only what sources described as “routine” information for a 20-year-old male. Thus far, investigators have turned up nothing to suggest that he had any accomplices or other support to carry out his deadly objective.

Butler County Sheriff tells ABC News he was not aware of suspect before shooting

Butler County Sheriff Michael Slupe spoke with ABC News on Tuesday about the response to the attempted assassination of former President Donald Trump.

When asked whether he heard radio traffic about a suspicious person at or near the rally ahead of the shooting, Slupe said, “I did not, and I wish I did.”

Slupe said he attended Saturday’s rally along with a number of his deputies.

He said that his office does not have a team of snipers, but that there is an emergency service unit “attached to” the Butler County District Attorney’s Office that is made up of officers from different agencies around the county.

Slupe said he did not know exactly how many of these emergency service officers were on the scene on Saturday.

Slupe defended the response by his deputies and called for the public to avoid passing judgment until the investigations conclude, noting that his office is not facilitating these probes.

“There’s several investigations going on, and at the end of the day, we’re all going to learn something from this,” Slupe said.

Scalise says Secret Service director should resign

House Majority Leader Steve Scalise said he believes Secret Service Director Kim Cheatle should resign.

“I’ve been very disappointed in her and her lack of candor,” Scalise told Politico. “I think the American people need to see whatever the answers are. Tough questions, you got to take the tough questions. You take a position like that … you can’t have a bad day.”

Scalise said the Secret Service “should have been out publicly right away” and addressing the press after the shooting.

“You had the local law enforcement giving a press conference, frankly, being asked questions that the head of the Secret Service should have been asked,” he said. “And she, you know, kind of was nowhere to be found during that period, and yet they took those tough questions. She’s got to answer tough questions. You can’t hide from them.”

Scalise was shot and wounded at a congressional baseball practice in 2017.

State police provided ‘all resources’ Secret Service asked for

The Pennsylvania State Police said it provided “all resources” the Secret Service asked for ahead of Saturday’s rally.

The Secret Service’s requests included about 30 to 40 troopers to help secure the inside perimeter, the state police said.

The state police said it “was not responsible for securing the building or property at AGR International,” which was the building from which the shooter fired from the roof.

Trump’s Secret Service protection had been increased prior to assassination attempt due to Iran threat: Sources

The Secret Service in recent weeks had increased Donald Trump’s security detail due to intelligence indicating there was an Iranian threat to assassinate the former president, according to three officials familiar with the matter.

There is no indication the plot was related to Saturday’s shooting.

The sources have suggested Iran has been making these types of threats since the assassination of Iranian military officer Qasem Soleimani in January 2020.

Trump Jr. recalls moment he learned father was shot

Donald Trump Jr. said he was fishing with his daughter on Saturday when his fiancée, Kimberly Guilfoyle, called to tell him that his father was shot.

“Kim calls me [and said], ‘Your father was shot,'” Trump Jr. recounted during a fireside chat with Axios.

But she had no other information to give, he said.

“It was 90 minutes before I even knew he was alive,” Trump Jr. said.

Trump Jr. said then he was able to speak to his father on the phone.

“Considering the heaviness of that moment, sort of gave me a window for some levity and. you know, I asked him, ‘Well, most importantly, like, how’s the hair?'” he said.

Trump Jr. said his father responded, “The hair is fine … a lot of blood in it, but it’s fine.”

“It was a heavy couple of hours, just that unknown,” Trump Jr. said. “And then you finally find everything’s OK, and then you sit down, and you start seeing the video when you’re watching the news. And it was like, the adrenaline dump leaves, you know. Sort of amazing how calm I was first, and then, it’s like, once that goes — ‘poof.'”

Trump Jr. said he believes his father is a changed man after the shooting.

“There are events that change you for a couple minutes and there’s events that change you permanently,” he said.

He also said he believes that there was a breach in security procedures at Saturday’s rally.

The bulletin also said that “lone actors” or small groups of extremists “likely will continue to view” political rallies and campaign events as “attractive targets.”

Gunman planned to attend local 4-year university this fall

Thomas Matthew Crooks, the 20-year-old suspected gunman, planned to attend Robert Morris University this fall, according to a school spokesperson.

Robert Morris University is a private, four-year university located outside of Pittsburgh.

Trump family member will attend shooting victim Corey Comperatore’s funeral

Eric Trump said there is “no question” that a Trump family member will attend the funeral of Corey Comperatore, who was shot and killed at the campaign rally on Saturday.

During an interview with Fox News on Monday night at the Republican National Convention, Eric called Comperatore’s death “unthinkable,” adding, “This is a person who loved Donald Trump, his family. He jumped on his children. It’s unthinkable what happened there.”

Comperatore, 50, was a firefighter and a father of two daughters, Pennsylvania Gov. Josh Shapiro said Sunday. He was from Sarver, Pennsylvania.

Comperatore “died a hero” when he “dove on his family” to protect them from the gunfire during the rally, his wife said, according to Shapiro.

Eric Trump indicates Secret Service director should step down after shooting

In his first interview since Donald Trump was shot at a rally Saturday, Eric Trump was asked if U.S. Secret Service Director Kimberly Cheatle should stay in her position.

“The head [of the Secret Service]? No, they should have had more resources,” Trump said.

“Listen, at the end of the day, we can’t get past the fact that somebody should not have gotten on a roof 130 yards away from the president of the United States — you know, ex-president of the United States, and soon to be president of the United States, with a high power rifle; that’s inexcusable,” Trump said.

Speaking with ABC News Chief Justice Correspondent Pierre Thomas, Cheatle called the shooting “unacceptable,” saying, “it’s something that shouldn’t happen again.”

In the days since the attack, Cheatle and the Secret Service have faced heightening scrutiny for failing to prevent the incident from happening, and even calls from some to resign.

Cheatle said she would not resign from her role.

Biden addresses trajectory of 2024 election after assassination attempt on Trump

President Joe Biden weighed in on if the assassination attempt on former President Donald Trump will impact the trajectory of the 2024 election.

In an interview with NBC’s Lester Holt, Biden was asked if he believes that this shooting has “changed the trajectory of this race,” to which Biden said, “I don’t know. And you don’t know either.”

“I’ve thought less about the trajectory of the race than two things. One, what his [Trump] health is. That was secure. Number one. And number two, what happens from here on in terms of the kind of coverage that the president and vice president and former president and new vice president get,” Biden said.

The president was also asked about his phone call with Trump after this past weekend’s shooting, which he described as a “very cordial” conversation.

“I told him how concerned I was and wanted to make sure I knew how he was actually doing. He sounded good. He said he was fine. And he thanked me for calling him. I told him he was literally in the prayers of Jill and me and I hoped his whole family was weathering this,” Biden said.

Secret Service director says police were inside building shooter was positioned on

In her first network interview since the assassination attempt on former President Donald Trump, U.S. Secret Service Director Kimberly Cheatle offered insight into the logistics surrounding the deadly shooting Saturday.

“It was unacceptable,” she said in an interview Monday with ABC News Chief Justice Correspondent Pierre Thomas. “And it’s something that shouldn’t happen again.”

Cheatle said that local authorities were tasked with securing the building where the alleged shooter fired the shots before being taken out by a Secret Service sniper, and confirmed that local police were present inside the building while the shooter was on the roof.

“In this particular instance, we did share support for that particular site and that the Secret Service was responsible for the inner perimeter,” Cheatle said. “And then we sought assistance from our local counterparts for the outer perimeter. There was local police in that building — there was local police in the area that were responsible for the outer perimeter of the building.”

She is expected to testify before the GOP-led House Oversight Committee next Monday, July 22.

He said that many people from the political spectrum have called him over the past 24 hours and described the moment he turned his head on stage to look at the screen, which ultimately could have saved his life.

“That reality is just setting in,” Trump said. “I rarely look away from the crowd. Had I not done that in that moment, well, we would not be talking today, would we?”

The world has now seen the image of the former president raising his fist with blood on his ear, and Trump said he did that because he wanted the country to know he was going to be OK. He wanted the Pennsylvania crowd to know that “America goes on, we go forward, that we are strong.”

Trump recalled, “The energy coming from the people there in that moment, they just stood there; it’s hard to describe what that felt like, but I knew the world was looking. I knew that history would judge this, and I knew I had to let them know we are OK.”

“He’s normal Trump,” Jackson said in Milwaukee Sunday night, adding that the former president is “really motivated and fired up” after the shooting.

Suspected rally gunman was member of local shooting club

The man suspected of taking aim at former President Donald Trump Saturday night was a member of a local shooting club, counsel for the club confirms to ABC News.

Thomas Crooks belonged to Clairton Sportsmen’s Club, in Clairton, Pennsylvania, roughly 12 miles south of Pittsburgh, which has a variety of shooting ranges.

“I can confirm that Mr. Crooks was a member of Clairton Sportsmen’s Club,” Robert S. Bootay III, attorney for the club, said in a statement.

“Beyond that, the Club is unable to make any additional commentary in relation to this matter in light of pending law enforcement investigations,” Bootay continued.

“Obviously, the Club fully admonishes the senseless act of violence that occurred yesterday. The Club also offers its sincerest condolences to the Comperatore family and extends prayers to all of those injured including the former President,” he said.

Biden says politics can never become a ‘killing field’ after Trump rally shooting

President Joe Biden spoke directly to the nation Sunday, saying the political landscape cannot be a “killing field” after the assassination attempt against former President Donald Trump Saturday.

“Disagreement is inevitable in American democracy,” Biden said, adding, “It’s part of human nature.”

“But politics must never be a literal battlefield or God forbid, a killing field,” Biden continued.

“I believe politics ought to be an arena for peaceful debate, to pursue justice, to make decisions guided by the Declaration of Independence and our constitution we stand for in America, not of extremism and fury, but of decency and grace,” Biden added.

During his address, Biden said that he spoke on the phone with Trump following the attack and that he’s “grateful” Trump was not seriously injured and doing well.

Biden ended his speech with a call for unity, saying, “Let’s remember we are the United States of America.”

“There is nothing, nothing, nothing beyond our capacity when we do it together,” he added.

Assassination attempt on Trump expected to be ‘exploited’ by misinformation: NYPD

The assassination attempt on former President Donald Trump “will likely be amplified in extremist messaging and heavily exploited by malicious actors,” according to an NYPD intelligence product obtained by ABC News.

The misinformation surrounding the attack is “aimed at fomenting division,” according to the Sunday bulletin.

“In the immediate hours after the shooting took place, multiple users on numerous online messaging platforms responded to the incident with support for the attack, overt calls for civil war, hostile rhetoric against FPOTUS Trump, threats against elected officials and generalized calls for retaliatory violence,” according to the bulletin.

Sources have said there has been an uptick in threats to elected officials around the country as a result of the attack.

Police spotted suspected shooter before attack on campaign event

Authorities outside the security perimeter of Donald Trump’s campaign event Saturday were alerted there was a man acting suspiciously before the shooting.

Local and state police, responsible for security outside that perimeter, began to search for a potential suspect, multiple sources briefed on the probe tell ABC News.

Within minutes, law enforcement spotted the suspected gunman on the roof, sources said.

It is unclear as of now, according to sources, whether this information was passed along to the U.S. Secret Service, which is responsible and focused on the security of the former president and the crowed inside the security zone.

A police officer saw the suspect on a rooftop and attempted to make it to the roof to engage the shooter, police sources said.

That officer was threatened when the gunman pointed his rifle at the cop, according to sources, who add that effort did not succeed as, moments later, shots rang out, targeting Trump.

Biden to give ‘forceful’ address to nation tonight, continue campaigning next week

President Joe Biden will deliver “a forceful and needed” address to the nation Sunday evening following the assassination attempt of former President Donald Trump on Saturday, a campaign official told ABC News.

Biden will address the “horrifying attack” and urge “every American to come together to not just condemn, but put to an end political violence in this country once and for all,” the official said.

In light of Saturday’s shooting, Biden’s campaign said they were “pausing all outbound communications and working to pull down our television ads as quickly as possible.”

The campaign official said next week, “The DNC and the campaign will continue drawing the contrast between our positive vision for the future and Trump and Republicans’ backwards-looking agenda over the course of the week.”

Suspicious devices found as investigators search for motive

In the ongoing investigation into the attempted assassination of Donald Trump Saturday, FBI officials said “suspicious devices” were found in the suspected shooter, Thomas Matthew Crooks’ car and home.

Another was found in his home, Rojek said, and both were described as rudimentary.

Crooks had no known history of mental illness, per the FBI. His family is cooperating with investigators.

Milwaukee PD addresses state gun laws ahead of RNC

Milwaukee police said they don’t have the authority to ban guns in the areas surrounding the Republican National Convention.

“Local ordinances in the state of Wisconsin do not supersede state law,” Milwaukee Police Assistant Chief Steven Johnson said during a press briefing Sunday with the U.S. Secret Service, noting that because Wisconsin is an open carry state, no jurisdiction can supersede that state law.

“Folks should be aware of that,” Johnson added.

RNC Coordinator Audrey Gibson told reporters that security officials took steps to “ban items they could ban” within the perimeter of the RNC, but “in terms of banning weapons in the outer perimeter, that is not within our purview,” she said.

Secret Service not expanding perimeter for RNC: Officials

During a press briefing Sunday, U.S. Secret Service officials addressed the assassination attempt against former President Donald Trump and the upcoming Republican National Convention following Saturday’s shooting.

“This is a national security event and that designation is the highest level that the federal government can determine,” RNC coordinator Audrey Gibson said.

“We are confident in the security plans in place for this event and we’re ready to go, it’s been an 18-month process,” Gibson continued, adding, “We’ve worked together to develop operational security plans for any and all access of security.”

Officials explained that the current Secret Service inner perimeter plan is the “largest inner perimeter that has been part of the convention” and that plans did not change following Saturday’s shooting.

Officials said there are no known articulated threats against the RNC.

Suspected shooter worked as dietary aide at nursing and rehab center

Suspect had no known mental illness history, his family is cooperating

Authorities “have not identified an ideology associated” with the suspected shooter, Thomas Crooks, FBI Pittsburgh Special Agent in Charge Kevin Rojek told reporters on a call on Sunday.

“We’re looking into his background, his day-to-day activities, any writings and social media posts that might help us identify what led to this shooting. And we have not seen anything threatening,” Rojek said.

Crooks had no known mental illness history, he said.

Crooks’ family is cooperating with federal authorities, officials said.

Offifcials told reporters they don’t have any insights on what the suspect’s actions were prior to opening fire at the shooting site, but said it’s something they are investigating.

Robert Wells, the FBI’s assistant director of the Counterterrorism Division, told reporters, “We are investigating this as an assassination attempt, but also looking at as a potential domestic terrorism act.”

The FBI has received more than 2,000 tips, according to Rojek.

Crooks’ gun and phone will be transported to the FBI lab in Quantico, Virginia, officials said.

Rojek also confirmed there was a suspicious device that was found in the suspect’s car and said the FBI is still analyzing what it is. Another device was found in the suspect’s home, according to the FBI. Rojek described both the devices as rudimentary.

The FBI is seeing an increase of violent threats online in the aftermath of the assassination attempt, FBI Deputy Director Paul Abbate said.

“We’ve seen individuals go online and attempt to mimic or pose as the shooter who obviously is now deceased,” Abbate said. “We’re also focused on the continuing efforts, which were already substantial, given that there are national special security events on the upcoming conventions in Chicago, in Milwaukee, to work with Secret Service in the lead to play our part in protecting the people and the facilities and events there, as well.”

FBI Director Christopher Wray called the assassination attempt an “attack on our democracy.”

“An attempt to assassinate a presidential candidate can only be described as absolutely despicable and will not be tolerated in this country,” Wray told reporters.

Shooting suspect was rejected from high school rifle club

The man suspected of shooting Donald Trump previously sought to join his high school’s rifle club, but was rejected and asked not to return, two students who were members of the team at the time told ABC News.

The suspect, Thomas Crooks, attended what was described as “preseason” for the rifle club, which is held before tryouts, but he did not make it to the tryouts, the two team members said. Both students said Crooks was a “bad shot,” with one adding that he wasn’t the right “fit.”

“He didn’t just not make the team — he was asked not to come back because how bad of a shot he was. It was considered like, dangerous,” classmate Jameson Myers told ABC News.

“On the first day of preseason, he basically couldn’t even hit the target,” Myers said.

The team’s coach declined to comment and referred questions to the school district. A spokesman for the school district did not immediately respond to a request for comment.

Gun traced to shooting suspect’s father, was legally purchased

The firearm recovered at the scene of the Trump assassination attempt was legally purchased by the suspect’s father, an urgent trace conducted by ATF found, according to multiple law enforcement sources.

The AR-15-style assault rifle was purchased by the suspect’s father in 2013, according to a source briefed on the investigation.

The shooter — identified by the FBI as Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania — had no military affiliation, according to the Pentagon.

There were what “appeared” to be explosives in the suspect’s car, which was parked outside the Trump rally, two sources told ABC News. One source said they looked like grenades, but the sources said they were awaiting forensic results about whether the items are actually explosives.

Suspect described as ‘lonely,’ ‘quiet’

Former classmates of the suspected shooter, 20-year-old Thomas Matthew Crooks, of Bethel Park, Pennsylvania, described him to ABC News as a student who was “quiet” and did not have many friends.

“He was somebody who came across as lonely a lot,” said Jameson Myers, who said he attended both elementary and high school with Crooks.

Myers described him as “more socially reserved” and someone who “didn’t have a ton of friends.”

But he said he never heard Crooks discuss politics or, specifically, Donald Trump.

“I was friends with him. He never acted, like, by any means, a political revolutionary,” Myers said. “Was a very nice, even sweet guy, from what I knew.”

Another classmate, Zoe Materkowski, said he was “just a quiet kid.”

Added Jason Kohler, a classmate: “He was a loner. He would sit alone at lunch.”

Classmate Robert Abraham described him as “smart” and “kind.”

I am grateful to the brave secret service agents and law enforcement officials who risked their lives to protect my husband.”

“A monster who recognized my husband as an inhuman political machine attempted to ring out Donald’s passion — his laughter, ingenuity, love of music, and inspiration,” she said. “The core facets of my husband’s life — his human side — were buried below the political machine. Donald, the generous and carrying man who I have been through the best of times and the worst of times.”

“When the time comes to look beyond the left and the right, beyond the red and the blue, we all come from families with the passion to fight for a better life together, while we are here, in this earthy realm,” she said.
