Asked by Bloomberg News anchor David Westin on Friday why Trump has not yet fired Sessions, who Westin notes serves "at the pleasure of the president," Starr predicted the president would face difficulties attempting to appoint Sessions's replacement.


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

"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 continued. "We would have Rod RosensteinRod RosensteinRosenstein, Sessions discussed firing Comey in late 2016 or early 2017: FBI notes Justice Dept releases another round of summaries from Mueller probe Judge rules former WH counsel McGahn must testify under subpoena MORE as the acting attorney general of the United States indefinitely."

Starr served on the 1998 Republican-led investigation of former President Clinton, who was eventually impeached by the House but not convicted by the Senate on charges of perjury and obstruction of justice.

Speculation has grown over whether Trump will fire Sessions or Mueller in recent weeks as Trump's tone on Twitter increasingly turned towards direct calls for the investigation to be ended by Sessions.

"Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further," Trump tweeted in early August.

The president has also frequently attacked Mueller and the FBI investigators working with the special counsel's office, whom he frequently refers to as "angry Democrats."

"Bob Mueller is totally conflicted, and his 17 Angry Democrats that are doing his dirty work are a disgrace to USA!" he added in the same tweet.
