South Carolina Sen. Lindsey Graham told Sean Hannity on Wednesday that President Trump is not going to fire Special Counsel Robert Mueller.

Graham said speculation that Trump could remove Mueller -- who is investigating possible collusion between the Trump campaign and Russia -- is a "manufactured problem."

Retiring Arizona Republican Sen. Jeff Flake on Wednesday vowed to pull support for all federal judicial nominees -- including 21 pending in the Judiciary Committee and 32 awaiting a vote on the Senate floor -- unless the Senate's GOP leadership permits consideration of legislation to expand protections for Mueller's job.

“President Trump is not going to fire Mueller. Mueller's going to be allowed to do his job,” Graham said. “And we need conservative judges on the bench, as many as we can, as often as we can get them. ... And at the end of the day, I am convinced that Mr. Mueller will be allowed to do his job.”

Graham added, “I have seen not one scintilla of evidence of collusion. The obstruction of justice thing never made any sense to me.”

Graham also said it would be "ironic" to see President Trump undo a harsh criminal justice law passed by President Bill Clinton in 1994.

Graham appeared to reference how the Clintons and Democrats writ large are seen as the people who want to help minorities and those who have served time in prison.

Hannity noted how, with the urging of Kim Kardashian West, Trump pardoned Alice Marie Johnson -- a grandmother who had been sentenced to decades behind bars for a drug conviction.

"Wouldn't it be ironic if it were Donald Trump that would fix the problems created by the 'three strikes, you're out' rule passed by Bill Clinton," Graham said. The law prescribes for harsher penalties for repeat offenders.

"Wouldn't it be ironic if [Trump] allowed thousands of African-American and Hispanic males a second chance," Graham said.

In 2015, Clinton said he regretted passing the Three Strikes Law, saying he "made a problem worse and I want to admit it," according to the BBC.
