The Hill: Attorney General Eric Holder said Tuesday that he didn't know if the use of enhanced interrogation techniques led to the discovery of Osama bin Laden's hideout in Pakistan. Rep. Dan Lungren (R-Calif.) asked Holder at a House Judiciary Committee hearing if any intelligence used to track bin Laden had been obtained during prison interrogations using controversial techniques such as waterboarding. Holder responded that there was a "mosaic of sources" that eventually led to bin Laden.
