Fox News host Greg Gutfeld blasted U.S. Chief Justice John Roberts after he issued a rare criticism of President Trump, who has called to impeach a federal judge that ruled against his administration in a recent immigration case.

Roberts’s statement, issued Tuesday, noted it has “been established that impeachment is not an appropriate response to disagreement concerning a judicial decision.”

“The normal appellate review process exists for that purpose,” the chief justice wrote.

Gutfeld, a vocal supporter of Trump and one Fox News’s top-rated hosts, pushed back on Roberts wading into the president’s fight with U.S. District Judge James Boasberg.

“When there are rapists and murderers invading our country, maybe a guy in a robe in D.C. can follow all the protocols, but Trump is the effing president of the United States who protects 300 million plus people,” Gutfeld said on Tuesday’s episode of “The Five.”

“He is a leader who does not have the luxury of opening up his little books to read.”

The comedian and cable news host told Roberts to “shut the F up.”

“This is something that a president has to do,” Gutfeld continued in the comments, first highlighted by Mediaite. “He has to do this. It blows my mind how wrong I was in 2016, or 2015, when Trump came down the escalator and we were … I was, ‘I can’t believe he said these things.’ Everything he said was right.”

He added, “They’re sending bad people. What did he say? They’re sending killers and rapists. Do you remember this? Some of them were good people. And now he’s sending them back.”

The Trump administration is arguing it has the legal authority to deport suspected members of the Tren de Aragua gang to El Salvador after Trump invoked the Alien Enemies Act of 1798 to remove Venezuelan migrants. Boasberg pushed back on the move, ordering the flights to be turned around.

However, administration officials said the flights were already out of U.S. territory and the judge no longer had authority to intervene.

The president was also pressed on his back-and-forth with the judge by Fox News’s Laura Ingraham. Trump suggested in the interview that aired Tuesday that he had not defied court orders and would not in the future.
