As Fox News reported :
“Surveillance videos taken on the night two Secret Service agents ran through a police scene after attending a party earlier this month may have been destroyed, Congressional sources told Fox News on Wednesday.
The disclosure comes as lawmakers on Capitol Hill have questioned the agency’s leadership in the wake of the March 4 incident, in which the agents were returning from a party for a departing spokesman, and drove into the scene of an active suspicious package investigation. (The package turned out to be a book.)”
