Senate Judiciary Committee Chairman Lindsey Graham (R-S.C.) once again made it clear that he sees no need to bring special counsel Robert Mueller to testify before his committee on the Russia investigation report.

After Attorney General William Barr finished testifying about the report and the investigation before the Senate Judiciary Committee on Wednesday, Graham was asked why he wouldn't be bringing Mueller in to do the same.

"Because I am not going to do any more," an exasperated Graham told Capitol Hill reporters. "Enough, already; it's over."

But, just because he doesn't plan to send Mueller a subpoena or open invitation, doesn't mean that the prosecutor won't have an opportunity to speak his mind to the committee.

"If there's any dispute about a conversation, then he'll come," Graham added to reporters, "but I'm not gonna retry the case ... it is over!"

Earlier, during the hearing, Graham said that Mueller would have a chance to testify on anything in Barr's testimony that he might find "misleading or inaccurate."

"I'm going to ask him, 'Is there anything you said about that conversation that he disagrees with?' And if there is, he can come and tell us," Graham said.

Graham's Democratic counterpart on the House Judiciary Committee is another story, entirely. House Judiciary Chairman Jerry Nadler (D-N.Y.) has already invited Mueller to appear before his committee, but the Department of Justice has been unwilling to set a date, according to Democrats.

Reported disagreements between Barr and Mueller over the outcome and findings of the Russia investigation made headlines again this week night with the release of a letter the investigator sent to Barr taking issue with the latter's four-page summary of the report.

During a line of questioning from Sen. Dick Durbin (D-Ill.) at the Wednesday hearing, Barr said that he had "no objection" to Mueller testifying.
