Senate Majority Leader Mitch McConnell, R-Ky., criticized Sen. Jeff Flake, R-Ariz., for withholding his vote on all judges until a vote on a bill to protect special counsel Robert Mueller comes to the floor, calling it a “futile gesture.”

“I’m perplexed, frankly, by his pushing for the Mueller protection bill,” McConnell said Monday at a Wall Street Journal CEO Council meeting, arguing that it has two problems. Namely, that it is “blatantly unconstitutional” and that it can’t pass the House or the executive branch.
