Acting Attorney General Matthew Whitaker said that as far as he has seen, special counsel Robert Mueller has handled the Russia probe correctly, Sen. Lindsey Graham said Thursday. Graham's remarks to an NBC News reporter came just after the senior Republican senator spoke with Whitaker in a closed-door meeting in Graham's office on Capitol Hill. "I don't think he's going to do anything unsavory," Graham said of Whitaker to a gaggle of reporters just after the meeting. Graham said Whitaker also told him that he sees no need to recuse himself from his role overseeing the special counsel's probe of Russian interference in the 2016 U.S. presidential election — a step increasingly demanded by Democrats and some legal experts.

The Justice Department, however, has already determined that it was appropriate for Whitaker to serve as the top U.S. law enforcement official in an acting role despite his having avoided Senate confirmation as a DOJ employee. DOJ spokeswoman Kerri Kupec told CNBC that Whitaker "had a good meeting day" with Graham, adding that the acting attorney general "is following the processes and procedures of the Department of Justice on all matters." Graham's comments Thursday aligned with the stance he took on Whitaker's appointment in an interview on CBS' "Face The Nation" over the weekend. "I think he was appropriately appointed legally, I don't think he has to recuse himself. I am confident the Mueller investigation will be allowed to come to a good solid conclusion, that there'll be no political influence put on Mr. Mueller by Mr. Whitaker to do anything other than Mr. Mueller's job," Graham said on the program. Whitaker became acting attorney general after President Donald Trump fired then-Attorney General Jeff Sessions shortly following the midterm elections, where Democrats won majority control of the House of Representatives and Republicans strengthened their Senate majority. Whitaker had served as chief of staff for Sessions, who had recused himself in March 2017 from overseeing investigations into Russian interference after he had drawn intense scrutiny for failing to disclose his contacts with Russian ambassador Sergey Kislyak in 2016.
