Representative Dan Burton repeatedly read remarks Brian McNamee had made, and each time the former trainer was forced to admit they were untrue.

"This is really disgusting. You're here as a sworn witness. You're here to tell the truth," the Indiana Republican said. "You're here under oath, and yet we have lie after lie after lie after lie, of where you've told this committee and the people of this country that Roger Clemens did things -- I don't know what to believe. I know one thing I don't believe, and that's you."
