“Don’t quit," recommended Bash on NBC's "Today Show" on Tuesday morning. “I think he should make the president man up and fire him.”

Bash served as chief of staff at the U.S. Department of Defense from 2011 to 2013 and the CIA from 2009 to 2011, advising former CIA chief Leon Panetta in both capacities.

Bash also added that Trump is "bullying" the attorney general online.

"It's astounding," Bash said to co-anchor Savannah Guthrie. "The president of the United States is online bullying the attorney general," said Bash. "He's trying to Twitter-shame him into quitting his post."

The commentary comes after a New York Times report last week in which the president said that he would never have chosen Sessions to be his attorney general if he had known he would recuse himself from the Russia investigation due to a conflict of interest.

“Sessions should have never recused himself, and if he was going to recuse himself, he should have told me before he took the job, and I would have picked somebody else,” Trump said.

Trump appeared to imply Sessions was disloyal during a speech to the Boy Scouts of America at its 2017 Jamboree in West Virginia on Monday.

“As the Scout law says, a scout is trustworthy, loyal — we could use some more loyalty, I will tell that you that,” the president said.
