Sen. Jeff Flake, R-Ariz., said Wednesday he won’t support any of President Trump’s pending judicial nominees until the Senate allows a vote on legislation to protect special counsel Robert Mueller.

“I have informed the majority leader that I will not vote to advance any of the 21 judicial nominees pending in the Judiciary Committee, or vote to confirm the 32 judges awaiting confirmation on the Senate floor, until S. 2644 is brought to the full Senate for a vote,” Flake said on the Senate floor.
