posted by Hannity Staff - 1.24.20 Former Congressman Trey Gowdy stopped by ‘Hannity’ Thursday night to weigh-in on the Democrats’ never-ending impeachment fantasy; saying former President Barack Obama could be a relevant witness in the Senate’s ongoing trial. “Part of impeachment is setting a precedent for what happens in the future… So is President Obama, because I would want to know whether or not Joe Biden had the authority of the President when he made that statement. Every time that clip plays of Joe Biden, I think of more reasons that he’s relevant as a witness,” said Gowdy. Watch Gowdy on ‘Hannity’ above.
