Secret Service chief noted a 'zero fail mission.' After Trump rally, she's facing calls to resign

The Secret Service and its director, Kimberly Cheatle, are under intense scrutiny after the assassination attempt on former President Donald Trump. Lawmakers and others across the political spectrum question how a gunman could have gotten so close to Trump during a rally last weekend in Pennsylvania. Cheatle has talked about how the Secret Service has a “zero fail mission.” She's facing calls to resign and will testify on Capitol Hill on Monday as congressional committees and the Biden administration have opened a series of investigations. President Joe Biden appointed Cheatle in 2022 to take over an agency with a history of scandals. She's worked to bolster diverse hiring, especially of women.
