Top Republican lawmakers are becoming increasingly vocal about ending special counsel Robert Mueller’s federal probe into Russian interference in the 2016 presidential election.

“They ought to wrap it up. It’s gone on seemingly forever and I don’t know how much more they think they can find out,” Senate Majority Leader Mitch McConnell said Thursday, according to the Washington Examiner.

It “has got to stop,” House Majority Leader Kevin McCarthy told Fox News about Meuller’s investigation.

House speaker Paul Ryan wants to “see it get wrapped up.”

“I think Director Mueller would be well advised to wrap up his investigation,” Republican Texas Sen. John Cornyn told reporters this week.

Unless Mueller wants to be “the main focal point of the midterm election, which again is not something the Department of Justice or FBI should be doing, then I think he needs to wrap it up,” Cornyn continued.

Republican South Dakota Sen. John Thune told Fox News last month that it’s “time for them to begin winding this down.”

McConnell has been publicly supportive of Mueller’s investigation of Russian interference in the 2016 election as well as possible collusion between Russia and President Trump.

“I have no idea. But I think it would be great if we got to a conclusion some time soon,” McConnell said in response to a question about a possible timeline for Mueller’s investigation.

Mueller’s probe started May 17 of last year and has produced 20 indictments. All have been unrelated to Trump campaign collusion with Russia or election meddling.
