Another Trump staffer bites the dust.

After a year of public criticism from President Donald Trump, Attorney General Jeff Sessions has resigned. Sessions handed in his resignation on Wednesday, according to CNBC.

Matthew Whitaker, Sessions’ chief of staff, will act as interim attorney general, according to Trump’s Twitter page.

Sessions became a Trump target when he recused himself in Robert Mueller’s Russian interference probe, which Whitaker once deemed a "witch hunt."

“I recused myself not because of any asserted wrongdoing on my part during the campaign,” Sessions said last April. “But because a Department of Justice regulation, 28 CFR 45.2, required it.”

Whitaker will now oversee the Mueller probe.

Trump has not been shy about his disdain for Sessions.

During an interview with The Hill, 45 refused to acknowledge Sessions as attorney general.

“I don’t have an attorney general. It’s very sad,” he said.

In addition to his issues with the Russia investigation, Trump said he was not “happy at the border.”

Trump has also stated that Sessions’ performance as AG was poor and criticized him for getting flustered.

“I’m so sad over Jeff Sessions because he came to me. He was the first senator that endorsed me. And he wanted to be attorney general, and I didn’t see it,” he said.

“And then he went through the nominating process, and he did very poorly. I mean, he was mixed up and confused, and people that worked with him for, you know, a long time in the Senate were not nice to him, but he was giving very confusing answers. Answers that should have been easily answered. And that was a rough time for him.”

South Carolina Senator Lindsay Graham also expressed disapproval of Sessions.

“The president's entitled to having an attorney general he has faith in, somebody that is qualified for the job, and I think there will come a time sooner rather than later where it will be time to have a new face and a fresh voice at the Department of Justice. Clearly, Attorney General Sessions doesn't have the confidence of the president,” Graham said.
