BREAKING: Donald Trump reacts to Secret Service Director Cheatle resigning after almost losing life

U.S. Secret Service Director Kimberly Cheatle resigned Tuesday in the wake of mounting pressure following the assassination attempt on former President Trump, Fox News confirmed.

Fox News reviewed the letter Cheatle sent to the U.S. Secret Service Tuesday morning, just a day after she taking bipartisan heat during testimony before the House Oversight Committee Monday and over a week after a would-be assassin Thomas Crooks attempted to take the life of Trump at his rally in Butler, Pennsylvania, on July 13.

"To the Men and Women of the U.S. Secret Service, The Secret Service's solemn mission is to protect our nation's leaders and financial infrastructure," Cheatle wrote in a letter to the agency. "On July 13th, we fell short on that mission."

Biden, who did not fire Cheatle in the 10 days since the shooting, said he is "grateful to DirectorKim Cheatle for her decades of public service," and that he will appoint a new director soon.

"As a leader, it takes honor, courage, and incredible integrity to take full responsibility for an organization tasked with one of the most challenging jobs in public service," Biden said. "We all know what happened that day can never happen again. As we move forward, I wish Kim all the best."

Cheatle said, though, that the "incident does not define us."

"We remain an organization based on integrity and staffed by individuals of exceptional dedication and talent," she wrote, adding that the agency "will move forward with our investigatory and protective mission in a steadfast manner."

"We do not retreat from challenge," she wrote. "However, I do not want my calls for resignation to be a distraction from the great work each and every one of you do towards our vital mission."
