Members of the House Select Committee on Benghazi will interview a key witness from the State Department this week, Chairman Trey Gowdy announced Tuesday.

Patrick Kennedy, the State Department’s undersecretary for management, signed off on the temporary diplomatic facility in Benghazi prior to the 2012 terror attack there that left four Americans dead. He also oversaw the agency’s record-keeping practices, presiding over Hillary Clinton’s decision to use a private server to shield all of her official communications while she served as secretary of state.
