Kimberly Chexer, director of the US Secret Service, said she would take full responsibility for the security vulnerabilities related to the attempted assassination of Trump. "The solemn mission of the Secret Service is to protect our country's leaders," Chetel will tell lawmakers on Monday. "We didn't do it on July 13th." On Monday, Chetel will make the above statement at a congressional hearing, where she will face the toughest questioning since the shooting incident. The hearing will last for several hours, with dozens of lawmakers asking questions, including some who are calling for her resignation. The shooting incident at Trump's campaign rally has created a crisis for the US Secret Service, which admitted over the weekend that it had rejected some requests for enhanced protection.
