Homeland Security Secretary Jeh Johnson says he has faith in Secret Service Director Joseph Clancy, but says Clancy has work to do to "straighten out" the beleaguered agency.

Johnson said he was "very upset" by a March 4 incident in which two off-duty Secret Service agents drove a government car through a secured area at the White House and nudged a temporary barrier, supposedly after a night of drinking. The car intruded in area where a suspicious item was being investigated.

Johnson told Congress Thursday that he personally went to the White House to review the scene and "look at the orange barrel that was moved out of the way."

He called Clancy a strong leader and said he is confident Clancy can "straighten the organization out."
