The Justice Department and the CIA's internal watchdog announced Saturday a joint inquiry into the spy agency's destruction of videotaped interrogations of two suspected terrorists as the latest scandal to rock U.S. intelligence gathered steam.

The review will determine whether a full investigation is warranted.

"I welcome this inquiry and the CIA will cooperate fully," CIA Director Mike Hayden said in a statement. "I welcome it as an opportunity to address questions that have arisen over the destruction back in 2005 of videotapes."

The House Intelligence Committee is launching its own inquiry next week. It will investigate not only why the tapes were destroyed and Congress was not notified, but also the interrogation methods that "if released, had the potential to do such grave damage to the United States of America," said Chairman Rep. Silvestre Reyes, D-Texas, on Saturday.

"This administration cannot be trusted to police itself," Reyes said.

The Senate Intelligence committee is also investigating.
