“The president’s been — he can be a handful — that’s just the way it is," Graham said while giving an endorsement of William Barr for attorney general.

“But he does ask people what they think,” Graham added, saying that the president asked him about potential attorney general nominees.

Graham said Barr was among the people he was asked about, and he told the president that Barr would be a “great choice.”

The Judiciary Committee, on which Republicans hold a majority of seats, approved Barr's nomination in a 12-10 vote on Thursday. Now, Barr needs a majority of the Senate to approve his nomination. Republicans hold a 53-47 majority, so Barr is expected to be confirmed as the new attorney general. He will replace Jeff sessions, who resigned in November.

"I think we need a new attorney general. I appreciate what Mr. Whitaker has done, but I think the time has come for new leadership in the department," Graham said before the vote.

Matthew Whitaker has been serving as acting attorney general. He was supposed to testify before the Judiciary Committee on Friday, but now says he might not after Democrats said they would subpoena him if he did not testify.
