A former Department of Justice prosecutor with a background in money laundering has joined the staff of Special Counsel Robert Mueller.

Attorney Kyle Freeny is the 17th lawyer known to be part of Mueller's team as he investigates President Trump's campaign and possible ties to Russia.

Politico reported Freeny was seen leaving federal court in Washington on Friday following the grand jury testimony of Jason Maloni, the the spokesman for former Trump campaign chairman Paul Manafort.

Freeny was seen leaving the courthouse with former Justice Department Criminal Division chief and Enron prosecutor Andrew Weissman and Civil Division appellate attorney Adam Jed, who is also a former clerk to Supreme Court Justice John Paul Stevens.

Freeny was working on the Justice Department's money laundering cases in their Kleptocracy Asset Recovery Initiative, which investigates the proceeds of foreign corruption.

In July, FBI agents executed an early-morning search warrant at Manafort's Alexandria,Va., condominium. Manafort has denied any wrongdoing.

However, Freeny's role in the broader Russia probe remains unclear.
