Members of Congress questioned the head of the Secret Service on Capitol Hill yesterday. Julia Pierson tried to explain how an intruder with a knife made it all the way to the entrance of the Green Room before he was stopped. At the hearing, sitting next to Julia Pierson, was Ralph Basham. He ran the Secret Service from 2003 to 2006. Before that, he was a Secret Service agent for over 25 years. He joins us to discuss the current Secret Service situation.
