At his best Wednesday, U.S. Rep. Trey Gowdy, R-S.C., made short work of a Democrat-friendly law professor testifying before Congress, even offering him some “free litigation advice.” The former prosecutor turned congressman was surgical in his questioning of Professor Charles Tiefer, who was brought before the House Judiciary Committee as an expert witness by Democrats — Tiefer has a history of being of service to the Democratic Party, according to The Blaze. “Professor Tiefer, would you seat a juror who referred to your client as an obscene body part?” Gowdy asked in his opening question.
