Secret Service Director Faces Inquisition Over Latest Breach

The director of the U.S. Secret Service will testify before a U.S. House committee Tuesday about a major security breach at the White House earlier this month.

Julia Pierson is expected to undergo tough questioning by lawmakers over the security breach, as well as several other embarrassing incidents involving the agency, which is responsible for protecting President Barack Obama and his family. 

The other incidents include a failure to immediately respond to a lone gunman who fired shots at the White House in 2011, a prostitution scandal involving agents on a presidential trip to Colombia in 2012, and a night of drinking in March that led to three agents being sent home from a presidential trip to Amsterdam.
