“Everyone tells me if you get one of these independent counsels it ruins your presidency. It takes years and years and I won’t be able to do anything. This is the worst thing that ever happened to me,” he added, according to notes from Jody Hunt, Sessions's chief of staff at the time.

Trump then reportedly became livid with Sessions, excoriating him for recusing himself from overseeing the probe and saying he should resign.

“How could you let this happen, Jeff?” Trump asked Sessions, adding that he had “let [him] down.”

Sessions recalled that Trump said to him, “you were supposed to protect me,” or “words to that effect,” according to the Mueller report.

The president and attorney general then agreed that Sessions would submit his resignation to the White House, according to Mueller's report. The next day, Sessions handed in a resignation letter to Trump, but the president said he wanted him to stay at the Department of Justice.

The president returned the letter over a week later with a notation saying, “Not accepted.”

Trump and Sessions were known to have an acrimonious relationship during Sessions’s tenure atop the Justice Department. The president frequently berated his attorney general over his decision to recuse himself from overseeing the Mueller probe due to prior meetings with Russia's former ambassador. Trump continued his criticism long after Sessions left his post in November.

“Jeff Sessions should be ashamed of himself for allowing this total HOAX to get started in the first place!” Trump tweeted in December.

Trump also repeatedly derided the Mueller investigation as a "witch hunt" throughout the nearly two year probe. Following the redacted report's release Thursday, the president said: "I'm having a good day."
