UNITED STATES - FEBRUARY 05: Panelists, from left, Randall Fort, assistant secretary to the director of National Intellegence, Robert Mueller, director of the U.S. Federal Bureau of Investigation, Mike McConnell, director of National Intelligence, Michael Hayden, director of the U.S. Central Intelligence Agency, and Michael Maples, director of the Defense Intelligence Agency, listen during a hearing before the Senate Intelligence Committee hearing in Washington, D.C., U.S., on Tuesday, Feb. 5, 2008. Hayden testified that waterboarding was employed in questioning three terror suspects because officials feared an attack and didn't know much about al-Qaeda. ``We used it against three detainees because of the circumstances at the time'' and it has since been discontinued, Hayden said.
