Sen. Josh Hawley (R-MO) revealed details on how unprepared security was at former President Donald Trump’s rally in Butler, Pennsylvania, in which he came within inches of losing his life.

The Secret Service has been under massive scrutiny since Trump narrowly survived the assassination attempt in July, with several investigations looking into the failures that allowed it to happen. Citing information that had been passed to him by whistleblowers, Hawley detailed that the agents protecting Trump at his rally were Homeland Security agents, not Secret Service agents, who only received a two-hour online training course before being deployed to guard the former president.
