President Donald Trump freshly criticized his own attorney general, Jeff Sessions, in an interview with the Hill, suggesting he’s frustrated with him on a variety of issues.

“I don’t have an attorney general. It’s very sad,” Trump told the Hill in a video interview. “I’m not happy at the border, I’m not happy with numerous things, not just this,” he said. Trump has long criticized Sessions for his decision to recuse himself from the Russia collusion investigation, and speculation that the president would fire him has been growing. The Hill says Trump demurred on whether he might one day fire Sessions. “We’ll see what happens,” Trump said. “A lot of people have asked me to do that. And I guess I study history, and I say I just want to leave things alone, but it was very unfair what he did,” he said, referring to the recusal decision.
