Jonathan Turley, a popular legal commentator and a law professor who holds the Shapiro Chair of Public Interest Law at George Washington University, had testified before Congress many times.

He’s even represented members of Congress in court, but key this week as the U.S. House opens hearings on whether Joe Biden should be impeached is the fact he’s testified before Congress during the Clinton impeachment, and the two failed impeach-and-remove schemes assembled by ex-House Speaker Nancy Pelosi against President Donald Trump.
