MSNBC's Joe Scarborough ripped Deputy Attorney General Rod Rosenstein early Thursday, calling him a "sainted figure, according to Trump hacks" whose "wisdom and knowledge came down from Mount Sinai."

"James Comey, the FBI director, went to Rosenstein, the sainted figure according to people in the Trump administration whose wisdom and knowledge came down from Mount Sinai and could not be ignored," said Scarborough, a GOP congressman in the 1990s.

"What makes this even worse is the fact that is the same man, Rod Rosenstein — and this needs to be investigated on Capitol Hill — had a meeting with the FBI director, with James Comey. James Comey let that man in that car know that he needed more money, he needed more resources and he needed to expand the investigation of collusion between Russia, Vladimir Putin and Donald Trump."

"So, Rod Rosenstein, the sainted figure, according to Trump hacks, gets this information, passes it along to Jeff Sessions who passes it along to Donald Trump, we are almost certain. And then what happens?" Scarborough asked.

"Donald Trump suddenly decides that Comey must be fired at once."

Rosenstein, who was confirmed in the Senate by a 94-6 vote two weeks ago, had recommended Comey's firing in a memo to the president.

"Although the President has the power to remove an FBI director, the decision should not be taken lightly," Rosenstein wrote. "I agree with the nearly unanimous opinions of former Department officials. The way the Director handled the conclusion of the email investigation was wrong."

"As a result, the FBI is unlikely to regain public and congressional trust until it has a Director who understands the gravity of the mistakes and pledges never to repeat them. Having refused to admit his errors, the Director cannot be expected to implement the necessary corrective actions," Rosenstein concluded.

"Morning Joe" panelist Mike Barnicle agreed with Scarborough's perspective on Thursday and made the argument for a special prosecutor.

"I spoke to several FBI agents, current, active FBI agents, and they all indicated they had great respect for Rosenstein," said Barnicle, a Boston Globe columnist.

"They felt he was an accomplished guy. He’s been a U.S. attorney for his entire adult life. But they say now that he has only one option to maintain his sterling credentials. And that is to appoint a special prosecutor."

"Morning Joe" has been highly critical of Trump since he took office in January, with Scarborough and co-host Mika Brzezinski calling him a "fake president" in recent weeks.

Scarborough and Brzezinski once faced accusations that they were too supportive of Trump during last year's White House race, when the billionaire candidate called into the program on multiple occasions.

The longtime MSNBC duo appeared to be in Trump's good graces as recently as New Year's Eve, when they were seen at a party at the president's Mar-a-Logo resort in Florida. Scarborough said the pair were there to talk to Trump about doing an interview on their show.

Trump has not appeared on "Morning Joe" since May 2016.
