"We have to do it. We have to hold the president accountable," Starr told Hill.TV's Buck Sexton and Krystal Ball on "Rising," when asked about Mueller's probe. 

"I've been harshly critical of the president for his criticisms in terms of the attorney general, as well as the Mueller probe," he said. 

"I have criticized or expressed concerns about some of the people around Bob Mueller, but I have very high confidence in Mueller himself," he continued. 

Trump has launched a series of attacks on Mueller's probe into Russia's election interference, fueling speculation that the president will fire Sessions, who has recused himself from the investigation. 

The president has also publicly directed Sessions to end the probe.

Starr on Friday said in an interview that there would be "hell to pay" if Trump moved to fire Mueller. 

“I think that there would be hell to pay if the president fired Mueller or ordered the firing of Bob Mueller,” Starr told Bloomberg. 

"Jeff Sessions I think is an honorable person who recused himself, so I think obviously the president has that prerogative, but it would be very hard to get a new attorney general confirmed," he said.
