From the New York Times:

A former C.I.A. officer, John Kiriakou, told ABC News and other news media organizations in 2007 that Abu Zubaydah had undergone waterboarding for only 35 seconds before agreeing to tell everything he knew.

Then he was waterboarded another 82 times.

Khalid Sheik Mohammad was waterboarded 183 times.

I think Obama has the right idea that a bipartisan 9-11 type committee should be formed instead of Leahy's truth commision because that might become too partisan.
