"I do believe the votes are there on the floor if we can just get a vote, and that's what I'm calling, let's just have a vote," Flake told CNN, asked about a measure that would protect Mueller from being fired without good cause.

"I don't know how we can be sanguine about what's going on over at the Department of Justice in terms of the Mueller probe. It's important to protect it," Flake added on Friday. 
 
Flake, joined by Coons and Booker, have gone to the Senate floor twice this month to try to get a vote and have been blocked both times.

Flake is pledging to oppose all of Trump's judicial nominees until he gets a vote on the bill, rankling his colleagues who have made confirming the president's picks their top priority. 
 
 
Flake's opposition is more problematic for Republicans on the Judiciary Committee, where they have a 11-10 majority. Unless Republicans can flip a Democrat on the committee, Flake's opposition leaves them unable to advance the president's nominees out of the panel by the end of the year.
 
 
"We need to protect the special counsel, it's important. Confirming judges is important," Flake, who is retiring at the end of this Congress, said. "I want to confirm more judges ... but this has to be priority now. And you have to take a stand. I have leverage because we have a narrow majority on the Judiciary Committee, so I'm using it."
