During both Republican and Democratic Administrations, congressional committees have investigated practices of the Office of White House Security, which is responsible for conducting security pre-screenings of candidates for White House employment and managing reports of security violations in the Executive Office of the President.
During these inquiries, at least five directors of the Office of White House Security – along with a few other White House Security Office Officials – have testified before Congress. In addition, FBI agents conducting background investigations have testified about concerns they had about awarding security clearances to specific individuals, and committee staff have reviewed the FBI background files of specific individuals.
