Missouri Sen. Josh Hawley announced whistleblower allegations sent to him claiming agents from the Homeland Security Investigations (HSI), partnered with the Secret Service on protective details, were improperly trained. 

According to Hawley, these improperly trained agents included those on security detail when former President Donald Trump was shot at a rally in Butler, Pennsylvania in July.

“Whistleblower allegations to my office report that the only training received by many HSI agents reassigned to work protective details is a single two-hour webinar on Microsoft Teams featuring pre-recorded videos,” wrote Senator Hawley in a letter to Acting Secret Service Director Ronald Rowe.

Hawley adds that the whistleblower believed the training left agents "ill-prepared."

A Republican, Hawley is a member of the Committee on Homeland Security and Governmental Affairs. He has taken a keen interest in the investigation of the assassination attempt on Trump, visiting the Butler site himself and publicizing multiple whistleblower allegations in the aftermath.

The previous allegations brought forth by Hawley include claims the Secret Service prevented extra security for the Trump rally in Butler, and that the roof the assassination attempt came from should have been staffed, but the post was abandoned. 

Trump was shot and wounded in his upper right ear by Thomas Matthew Crooks, a 20-year-old from Pennsylvania who fired eight rounds from an AR-15-style rifle from the roof of a nearby building.

Crooks also killed one audience member and severely injured two others. He was killed at the scene.

In a statement following the shooting, Trump thanked the Secret Service for its protection, writing "I want to thank The United States Secret Service, and all of Law Enforcement, for their rapid response on the shooting that just took place in Butler, Pennsylvania...It is incredible that such an act can take place in our Country."
