Former Trump administration strategist Steve Bannon is threatening to go after almost every Republican senator up for re-election next year,
Bannon says he and his far-right website, Breitbart News, will support primary challengers to every GOP senator except Ted Cruz of Texas.
Bannon says he's going to launch a war against Republicans who aren't loyal to Trump. Bannon's hit list includes Republican senators who have supported Trump and his agenda, including Orrin Hatch of Utah, Roger Wicker of Mississippi, John Barrasso of Wyoming, and Deb Fischer of Nebraska.
Bannon says he will only support candidates who agree to vote against Mitch McConnell as majority leader and vote to end Senators' ability to use the filibuster to block legislation.
