WASHINGTON, DC - SEPTEMBER 21: House Judiciary Committee Chairman Bob Goodlatte (R-VA) (L) and ranking member Rep. John Conyers (D-MI) hold a hearing to hear from Internal Revenue Service Commissioner John Koskinen in the Rayburn House Office Building on Capitol Hill September 21, 2016 in Washington, DC. Despite the lack of evidence against him, Koskinen is facing impeachment threats from conservatives in the House of Representatives for his role in the destruction of computer backups containing thousands of emails sought by Congress in its investigation of political targeting.
