Kimberly Cheatle handed over her resignation as the head of the Secret Service on Tuesday. This just over a week after her agency was hit with a lot of criticism over the attempted assassination of former President Trump.

In a House Oversight Committee hearing on Monday Cheatle acknowledged the attempt on Trump’s life as a “colossal failure” on hers and the Secret Service’s part.

“Thinking about what we should have done differently is never far from my thoughts,” she said.

Among those who watched the hearing was Rep. Erin Houchin (R-IN-9th) who told “The Todd Starnes Show” on Tuesday that Cheatle’s resignation should have come much sooner given the gravity of what happened.

“That was a disastrous hearing. She wouldn’t answer any questions,” Houchin said. “The buck stops with her. She is ultimately responsible. She cannot be in charge of investigating her own failure. So, I’m happy she resigned. It should have happened immediately.”

Houchin said she is eager to see the results of an independent investigation of the incident.

Earlier this month, Matthew Crooks was able to take a position on top of a building near where a rally in Pennsylvania was happening and got several shots off nearly hitting Trump, and killing a man in the audience behind him. Crooks ended up being shot and killed by Secret Service agents soon afterward.

“It’s terrifying to think that a 20-year-old was able to take that shot within 130 yards of President Trump,” Houchin added. “It’s infuriating that the Secret Service had eyes on him for an hour before that.”

Therein lies the failure, according to Houchin.

“The Secret Service’s solemn mission is to protect our nation’s leaders. On July 13th, we failed,” Cheatle said in the Monday hearing. As the Director of the United States Secret Service, I take full responsibility for any security lapse.”
