Secret Service director opens testimony with frank admission: 'We failed' – but won't resign

Secret Service Director Kimberly Cheatle opened her testimony to Congress with a frank admission that her agency "failed" in its mission to protect former President Trump.

Cheatle testified before the House Oversight Committee on Monday, facing a grilling from Republican and Democratic lawmakers alike. Several GOP lawmakers have called on her to resign, though she has so far refused.

"The Secret Service's solemn mission is to protect our nation's leaders. On July 13, we failed," Cheatle said in her opening statement.
