Head of the OLC said waterboarding was torture, chased out of government.

Remember, this is the guy who was responsible for rendering the official US government judgement (Office of Legal Counsel) as to whether waterboarding was torture.

A senior Justice Department official, charged with reworking the administration's legal position on torture in 2004 became so concerned about the controversial interrogation technique of waterboarding that he decided to experience it firsthand, sources told ABC News.

Daniel Levin, then acting assistant attorney general, went to a military base near Washington and underwent the procedure to inform his analysis of different interrogation techniques....

Levin, who refused to comment for this story, concluded waterboarding could be illegal torture unless performed in a highly limited way and with close supervision....

And what happened to Levin?

In December 2004, Levin released the new memo. He said, "Torture is abhorrent" but he went on to say in a footnote that the memo was not declaring the administration's previous opinions illegal. The White House, with Alberto Gonzales as the White House counsel, insisted that this footnote be included in the memo.

But Levin never finished a second memo imposing tighter controls on the specific interrogation techniques. Sources said he was forced out of the Justice Department when Gonzales became attorney general.
