Secret Service director Kimberly Cheatle said her agency failed in its mission to protect former president Donald Trump during a highly contentious congressional hearing with politicians of both major political parties demanding she resign over security failures.

In her first congressional hearing over the July 13 assassination attempt, Ms Cheatle repeatedly angered officials by evading questions, citing ongoing investigations.
