Watch live: Pennsylvania state police chief testifies before House on Trump shooting

Colonel Christopher Paris, commissioner of the Pennsylvania State Police, is slated to testify before the House Homeland Security Committee Tuesday on the shooting at former President Trump's rally in the Keystone State earlier this month. Trump was bloodied after a bullet pierced his ear at a campaign rally outside Pittsburgh just over a week ago, in what authorities are investigating as an assassination attempt. The shooting took place shortly after Trump had taken the stage in Butler, Pa. The suspected shooter and one rally attendee were killed, according to law enforcement. The Secret Service has come under intense scrutiny following the incident, and many have called on Director Kimberly Cheatle to resign. She testified Monday before the House on the failed assassination attempt. Tuesday's event is scheduled to begin at 10 a.m. EDT. Watch the live video above.
