FILE - In this Oct. 30, 2017 photo, Senate Foreign Relations Committee Chairman Sen. Bob Corker, R-Tenn., speaks during a Senate Foreign Relations Committee hearing on "The Authorizations for the Use of Military Force: Administration Perspective" on Capitol Hill in Washington. Democrat James Mackler says he's dropping out of the U.S. Senate race in Tennessee to replace Corker, a move that appears to clear the path to the Democratic nomination for former Gov. Phil Bredesen.
