House Judiciary Chairman Robert Goodlatte and Rep. Trey Gowdy, House Oversight and Government Reform chairman, both of whom are retiring next week, sent a letter to the Justice Department and Senate Majority Leader Mitch McConnell saying they reviewed thousands of documents and conducted interviews that "revealed troubling facts which exacerbated our initial questions and concerns." Republicans have said since the election that they believe Justice officials were biased against President Trump when they started an investigation into his ties to Russia and cleared Clinton in a separate probe into her email use.
