Fani Willis and Jack Smith are likely tag-teaming with Mark Meadows as a witness: Expert

Special counsel Jack Smith and Fulton County District Attorney Fani Willis may share Mark Meadows as a cooperating witness now that he's reached an immunity agreement with federal prosecutors, according to a legal expert.

Meadows has spoken with federal investigators at least three times, including once before the grand jury that indicted Donald Trump in the Jan. 6 case, and the special counsel has agreed not to use any of the evidence he provided to charge him in the case.

But Willis could be coordinating with Smith to make sure he can testify in that federal case without complicating matters in Georgia, reported Newsweek.

"If Smith has granted Meadows immunity, one wonders if there has already been co-ordination with Georgia on the strategy," said Peter Shane, a constitutional law specialist at New York University.

"Meadows' testimony could be a huge blow to Trump because he was right in the center of the action, so to speak, and would be able to provide first-hand accounts of Trump's actions.

"If Smith has granted Meadows immunity, it will also have implications for the Georgia case. Although I don't think Smith can grant Meadows transactional immunity from a Georgia charge, Smith's immunized D.C. testimony itself cannot be used as evidence in a Georgia prosecution."

Willis would have to show that any evidence in Meadows' case in Georgia was developed independently from leads teased out by federal investigators, and his immunity deal may prevent him from pleading the Fifth Amendment.

"The extent of immunity may be subject to bargaining with a witness, but it need not be," Shane said. "A prosecutor can essentially prevent a witness from 'taking the Fifth' by unilaterally immunizing his or her testimony."
