Washington (CNN) Sen. Jeff Flake warned that he and a "number of senators," are prepared to block President Donald Trump's judicial nominees if there is no action in the Senate on tariffs and other key issues.

"I do think that unless we can actually exercise something other than just approving the President's executive calendar, his nominees, judges, that we have no reason to be there. So I think myself and a number of Senators, at least a few of us, will stand up and say let's not move any more judges until we get a vote, for example, on tariffs," the Arizona Republican said on Sunday in an interview with ABC News' George Stephanopoulos.

This is not the first time Flake, who sits on the Judiciary Committee, has threatened to block Trump's judicial picks.

Last week, Flake told CNN it was something that was being discussed.

Currently, Republicans hold a slight majority on the committee, 11-10, which Judiciary Chairman Chuck Grassley has noted could pose a problem for passing nominees if even one Republican chose not to vote.
