SCOTTSDALE, Ariz. (AP) — Former presidential strategist Steve Bannon doubled down on his criticism of the GOP establishment at a Tuesday night fundraiser for a challenger to Arizona's incumbent Sen. Jeff Flake. Bannon heaped disdain on Senate Majority Leader Mitch McConnell and other incumbent Republicans, saying they failed President Donald Trump by not backing his agenda and are openly critical of their own president. "If you saw how they try to rip him apart every day, how they are trying to destroy him every day," Bannon said.
