Arizona Sen. Jeff Flake appeared on CNN’s State of the Union on Sunday after Deputy FBI Director Andrew McCabe was fired on Friday.
Flake was asked if Republicans would push back if President Trump took actions to fire special counsel Robert Mueller
"I hope so,” Flake said. “I mean talking to my colleagues all along it was — you know once he goes after Mueller, then we’ll take action. I think that people see that as a massive red line that can’t be crossed.”
