I watched the O'Reilly interview.
O'Reilly was backing him into a corner with questions, and Ritter looked highly uncomfortable.
He had the look of a person who knew he was lying and didn't believe what he was saying but at the same time knew that the consequences of not keeping up the lie were terrible.

Ritter did look very, very uncomfortable, I agree. But O'Reilly is a bulldog; he knew what he was getting into.
