Jeremy Scahill, national security reporter for The Nation, appeared on Current TV's Countdown with Keith Olbermann Thursday night to discuss the latest revelations about waterboarding and other "water treatment" torture practices used by the Department of Defense.

"What we are learning is more sick details of torture tactics that most certainly were authorized and advocated at the highest levels of the Bush administration," he said.

Scahill also noted that Obama has an "extremely poor record" of holding U.S. agents accountable for alleged acts of torture.
