The House Judiciary Committee’s impeachment hearings on Wednesday featured testimony from four law professors on the constitutional standards for impeachment. The witness called by the Republicans, professor Jonathan Turley of George Washington University Law School (where I teach a course on white-collar crime), argued that the record concerning the Ukraine scandal does not establish impeachable conduct by President Trump. Among his claims was that Trump’s behavior toward Ukraine would not constitute bribery under federal law. He’s wrong.
