President Trump slammed Democratic Senate candidate Phil Bredesen at a rally on Tuesday, claiming the former Tennessee governor would be a “total tool” of congressional Democratic leaders if he wins the seat this fall.

The Tuesday night rally in Nashville was intended to help Rep. Marsha Blackburn, who is running against Bredesen to fill retiring GOP Sen. Bob Corker’s seat. But the president spent most of his time criticizing Blackburn’s opponent and railing against Democratic leaders for their recent attacks against his rhetoric on immigration and MS-13.
