Secret Service chief will be questioned over security failures before Trump assassination attempt

The Secret Service director is set to testify before a congressional committee as calls mount for her to resign over security failures at a rally where a 20-year-old gunman attempted to assassinate former President Donald Trump. Monday's hearing will be Director Kimberly Cheatle’s first appearance before lawmakers since the July 13 Pennsylvania rally shooting that left one spectator dead. Trump was wounded in the ear and two other attendees were injured after Thomas Matthew Crooks climbed atop the roof of a nearby building and opened fire. Lawmakers have been expressing anger over how the gunman could get so close to the Republican presidential nominee when he was supposed to be carefully guarded.
