Jeff Flake: GOP needs to stand up to Trump more forcefully

Sen. Jeff Flake, R-Ariz., on Sunday called on Republicans in Congress to more forcefully push back against President Donald Trump and said there is growing concern behind the scenes that the president could take action against special counsel Robert Mueller. And, he said, Republicans are growing increasingly concerned privately that Trump could fire Mueller. “I can tell you behind the scenes there is a lot of alarm,” Flake said. “There is concern that the president is laying the groundwork to move on Bob Mueller or [Deputy Attorney General Rod] Rosenstein, and if that were to happen, obviously, that would cause a constitutional crisis."
