WASHINGTON (AP) - President Donald Trump is barnstorming for the Republican Senate candidate locked in a tight race in Tennessee.

The president appeared at a rally in Johnson City to support U.S. Rep. Marsha Blackburn, who is facing Democratic former Gov. Phil Bredesen. They are competing for the seat currently held by retiring Republican Sen. Bob Corker.

Trump declared that Blackburn would be a "true fighter" for Tennessee while her opponent, if elected, could make Democrat Chuck Schumer the new Senate majority leader. Republicans hold a narrow 51-49 advantage in the Senate and are trying to hold onto their majority.

As the prospects of the GOP keeping the House of Representatives appear to be fading, the president has accelerated his campaigning in support of Republican Senate candidates in recent weeks.
