 Maryland's lone Republican in Congress calling for the resignation of Secret Service Director Kimberly Cheadle following the attempted assassination of former President Donald Trump. Andy Harris says it's the responsibility of the Secret Service to make sure that every venue is safe, and the agency failed to secure the perimeter in last week's rally. He says the Secret Service should never have allowed a clear line of fire from a rooftop 130 yards from the person who's probably going to be the next president of the United States.
