Deputy Attorney General Rod Rosenstein, who oversees the special counsel’s probe of Russian meddling in the 2016 presidential election, is planning to leave, according to reports.

The Associated Press, quoting a source who wasn’t identified, said that Rosenstein was waiting for William Barr to be confirmed as the next attorney general before packing it in.

But NBC reported that Rosenstein planned to stay until Mueller’s investigation is finished.

Whatever the timeline, Sen. Lindsey Graham said Mueller shouldn’t worry about Barr interfering in his probe.

“I can assure you he has a very high opinion of Mr. Mueller and he is committed to letting Mr. Mueller finish his job,” Graham said.

In fact, he said Barr told him that he and Mueller worked together when Barr was George H. W. Bush’s attorney general between 1991 and 1993 and Mueller ran the department’s criminal division.

Graham said the two men were “best friends,” have known each other for 20 years and their wives even attend bible study together.

Mueller also attended the weddings of two of Barr’s daughters.

“I didn’t know that they were that close personally,” Graham said.

Barr faces a confirmation hearing before the Senate Judiciary Committee next week and could be in place as soon as February.

Rosenstein plans to leave at some point after that — though no date has been set, by the AP’s account.

There is no indication that Rosenstein, the No. 2 Justice Department official since April 2017, was forced out amid his tenuous relationship with President Trump, who blames him for appointing Mueller.

White House spokeswoman Sarah Huckabee Sanders on Wednesday said Rosenstein had always planned to stay around two years and wants to help with the transition to a new AG.

“I don’t think there’s any willingness by the president or the White House to push him out,” Sanders told Fox News. “My guess is he is making room for the new attorney general to build a team that he wants around him.”
