U.S. Secret Service Director Kimberly Cheatle testified for hours on Capitol Hill Monday, facing a grilling from lawmakers on both sides of the aisle over the agency’s lapse in security that enabled the assassination attempt on former President Trump. 

Cheatle testified before the House Oversight Committee, led by Chairman James Comer, R-Ky., after he subpoenaed her to appear.

REP. MACE CALLS 'BULLS---' ON RESPONSE FROM SECRET SERVICE DIRECTOR CHEATLE

Cheatle testified before the House Oversight Committee Monday, just over a week after a would-be assassin Thomas Crooks attempted to take the life of Trump at his rally in Butler, Pa. on July 13. 

Trump, during his rally, ever-so-slightly turned his head—narrowly missing the bullet shot by 20-year-old suspect Crooks’ AR-15-style rifle by just a quarter of an inch. The bullet hit him, instead, in his upper right ear.

The bullet killed firefighter, father and husband Corey Comperatore as he protected his family from the shots, and severely injured two others. 

Cheatle admitted under oath that the Secret Service "on July 13th, we failed." 

Here are the top five moments from the highly-anticipated hearing: 

Cheatle told the House Oversight Committee that "on July 13th, we failed" when it came to her agency's handling of the assassination attempt on the former president and the shooting at his Butler, Pa. rally. 

"As the director of the United States Secret Service, I take full responsibility for any security lapse of our agency," she continued.

"We must learn what happened, and I will move heaven and earth to ensure that an incident like July 13th does not happen again," Cheatle also said. "Our agents, officers and support personnel understand that every day we are expected to sacrifice our lives to execute a no fail mission."

House Oversight Committee Chairman James Comer, R-Ky., called on Cheatle to resign, along with other Republican lawmakers. 

But Democrats called for her resignation as well, including Rep. Ro Khanna, D-Calif., who said, "If you have an assassination attempt on a president or a former president or a candidate, you need to resign."

Cheatle has maintained that she will not resign, and said she is committed to getting answers on the massive security failure for the American people. 

TIMELINE: TRUMP ASSASSINATION ATTEMPT

Rep. Greg Steube, R-Fla., says he plans to introduce articles of impeachment against her.

"In light of Kimberly Cheatle’s unacceptable handling of the Trump assassination attempt, her disastrous appearance before the House Oversight committee today, and her refusal to resign, we have no choice but to impeach," Steube said in a post on X. "I will be filing articles of impeachment against Kimberly Cheatle this afternoon."

And Rep. Anna Paulina Luna, R-Fla., accused Cheatle of perjuring herself and stonewalling members of the House Oversight Committee, telling her protectees are "sitting ducks" with her in charge.

Rep. Nancy Mace, R-S.C., told Secret Service Director Kimberly Cheatle on Monday that her response that she had "no idea" how her opening statement for today’s House Oversight Committee hearing on the Trump rally shooting got leaked to media agencies is "bulls---." 

The fiery remark from the South Carolina lawmaker came after Cheatle was directed by Mace to answer a series of yes or no questions on the Secret Service’s response to the attempted assassination of former President Trump in Pennsylvania, in which Cheatle said "yes" to it being a "colossal failure," and a tragedy that could have been prevented. 

"Would you say leaking your opening statement to Punchbowl News, Politico’s Playbook and Washington Post several hours before you sent it to this committee as being political? Yes or no?" Mace asked Cheatle. 

"I have no idea how my statement got out," Cheatle responded. 

Mace fired back: "Well that’s bulls---." 

Mace started mentioning news articles published between 5 and 7 a.m. ET, about three to four hours before she said the House Oversight Committee received Cheatle's statement.

Mace then asked Cheatle, "Have you provided all audio and video recordings in your possession to this committee, as we asked on July 15? Yes or no?"  

SECRET SERVICE DIRECTOR OPENS TESTIMONY WITH FRANK ADMISSION: ‘WE FAILED’ -- BUT WON’T RESIGN 

"I would have to get back to you," Cheatle said. 

"That is a no. You're full of s-- today. You're just being completely dishonest," Mace told Cheatle, before being interrupted with a call for decorum inside the hearing room at the Rayburn House Office Building on Capitol Hill.

Secret Service Director Kimberly Cheatle on Monday said that "for the event in Butler, there were no requests that were denied" from former President Trump's team. 

"They asked for additional help in some form or another. You told them no. How many times did you tell them no? And what'd you tell them no to?" Rep. Jim Jordan, R-Ohio, asked Cheatle, referencing comments made by Secret Service spokesperson Anthony Guglielmi. 

"What I can tell you is that in generic terms, when people when details make a request, there are times that there are alternate ways to cover off on that threat or that report," Cheatle responded. 

Cheatle testified Monday that she called former President Trump after the shooting to apologize. 

She stressed, though, that the Secret Service and "the people that are in charge of protecting the president on that day would never bring the former president out if there was a threat that had been identified." 

Trump told "Jesse Watters Primetime" in an interview that aired Monday night that Cheatle came to see him in the days following the assassination attempt.

"It went very nicely. She was very nice, I thought. But, you know, somebody should have made sure there was nobody on that roof," he said.

So, it's weird Joe Biden hasn't been seen since they tossed his carcass from Air Force One last Wednesday. Can we at least get proof of life? Maybe have him pose holding a copy of today's paper? But then again, we've been asking for proof of life from Joe for years. Got nothing. So after years of watching him deteriorate and years of the media Democrat complex covering it up, Joe admits he's not up to the demands of campaigning, like traveling, speaking and not dying. But now they're in a pickle. 

If Joe Biden's too far gone to campaign, how can he remain commander-in-chief until January 20th? Shouldn't they put him on like an ice floe and give it a shove before his addled brain starts World War III? But if Joe can still do the job, then didn't we just witness a ‘coup’ orchestrated by Obama, Clooney, the big coastal donors and the media who just replaced a candidate simply because he was polling below Trump, which according to Dems means he was literally polling below Hitler. But talk about election interference. Someone get Joe Scarborough on the phone, but don't call his landline, he pulled the cable from the wall to make a noose. 

Look, Biden won those delegates, and that means he's the nominee. And like his toy fire truck, you can't take it away from him because it's his. Well, I guess you could take it away from him because they just did. Look, Trump got the nomination after being tested. In fact, there was quite a crowd on their debate stage, although half that crowd was Chris Christie. But the fact is, Trump got the nomination and no one could take it from him. But not so on the left. 

LOCKING IT UP: TRUMP CLINCHES 2024 REPUBLICAN PRESIDENTIAL NOMINATION DURING TUESDAY'S PRIMARIES

Just ask Bernie who the Dems hip-checked out of a presidential primary victory twice. And for a man his age, a broken hip could be fatal. So it was polling that got Biden out. A bunch of nameless number crunchers just anointed a new candidate. It wasn't because Biden's IQ dropped lower than his body temperature. If that was the standard, how can this woman be the replacement?

COMPILATION OF KAMALA HARRIS CLIPS

That's the laugh of a woman who loves school busses, the shorter the better. So they got by now because it looked like they were going to lose. That's anti-democratic. There's the rub. If they say it wasn't because Biden was going to lose, but because of his impairment, then he has to resign because then he's unfit to run and how the hell can he handle foreign policy when he's loopy? Then Dems should be saying the same words I hear at an ugly man convention: ‘get out of here.’ But if they say he is fit to be president, then why drop out of the race? You see, they painted themselves into a corner and of all places, the Oval Office. 

DEMOCRATS THROWN INTO CHAOS AS THEY FACE TIGHT DEADLINE TO REPLACE BIDEN

The system is delegates nominate a candidate, not delegates nominate a candidate until he doesn't look like he's going to win. That's an attack on democracy. They're overriding the voters. If that had been the standard on the right, Trump would have been ousted in 2016, and we likely would have gotten four years of Hillary and me and Jesse would have been found in the trunk of a car. Now, there could be something else going on here. Is there more to Joe dropping out than we know? Does it have something to do with Butler, Pennsylvania? I'm not suggesting the Dems tried to have Trump killed, of course. Hillary's retired. And she can't climb a slanted roof without twisting a kankle. 

But remember, Secret Service Director Cheatle was on Joe Biden's security detail. Jill reportedly pushed for Cheatle to get that top job. They're a perfect pair. A DEI hire gets your shot, then a phony doctor can give you fake first aid. But what if, when resources are allotted, favorites are played with experience and manpower? It's pretty clear the White House didn't take threats to Trump seriously. 

Could this have been negligence by derangement? A shared antipathy for Trump? So it looks like the Dems are embracing Kamala, who Joe has endorsed, although at this stage he mistakes her for Oprah. But Kam faces a dilemma. She can't possibly pick a VP more competent than she is. She can't afford to be overshadowed. So where is she going to find a politician who is even more clueless and incompetent than she is? Is there someone worse out there? Oh, wait a minute. I've got an idea. Kamala, Joe, just trade places.
