General Michael Hayden, Central Intelligence Agency director, was grilled on Capitol Hill on Tuesday over the destruction of videotapes showing the interrogation of two al-Qaeda members.

The CIA has come under intense scrutiny following the revelation that interrogators videotaped the questioning of Abu Zubaydah, an alleged 9/11 planner, and Abd al-Rahim al-Nashiri, the alleged mastermind of the 2000 bombing of the destroyer USS Cole in Aden, and later destroyed the tapes.
