 The director of the Secret Service is scheduled to appear before the House Oversight Committee today. Kimberly Cheadle is expected to be pressed about security failures and the attempted assassination of former President Donald Trump at an outdoor rally in Butler, Pennsylvania, earlier this month. Trump was grazed by a bullet on his right ear. One rally attendee was killed and two others were wounded before a Secret Service sniper killed the gunman on the roof of a nearby building.
