OK, trying to be objective and listening to what Cain said in the debate and what he said on the Neil Boortz program - I don't interpret a "lie" coming out of this story. If anything, Cain is backpeddling away from his previous statements. He clearly indicated an audit of the Federal Reserve was unnecessary and a waste of time in the audio clip. In the debate, he more or less said, "go ahead, that's fine if you want to audit them."
Backpeddling, not lying.
