The AP has released information on how exactly the U.S. government got the tip to where Osama Bin Laden was hiding out. President Obama stated last night that he had gotten the tip back in August but didn’t say how. Now we know who lead us straight to Bin Laden’s location. Find out who it was after the jump.

Officials say CIA interrogators in secret overseas prisons developed the first strands of information that ultimately led to the killing of Osama bin Laden.

Current and former U.S. officials say that Khalid Sheikh Mohammed, the mastermind of the Sept. 11, 2001 terrorist attacks, provided the nom de guerre of one of bin Laden’s most trusted aides. The CIA got similar information from Mohammed’s successor, Abu Faraj al-Libi. Both were subjected to harsh interrogation tactics inside CIA prisons in Poland and Romania.

The news is sure to reignite debate over whether the now-closed interrogation and detention program was successful. Former president George W. Bush authorized the CIA to use the harshest interrogation tactics in U.S. history. President Barack Obama closed the prison system.
