Davis Polk & Wardwell white-collar criminal defense partner Greg Andres in New York has become the latest addition to special counsel Robert Mueller III's investigative team looking into potential Russian interference in the 2016 U.S. presidential election.

Reuters, which broke the news late Tuesday of Andres' new role, noted that he will be the 16th lawyer added to Mueller's team since the former Wilmer Cutler Pickering Hale and Dorr partner was appointed in May by deputy attorney general Rod Rosenstein to probe possible links between the Russian government and individuals affiliated President Donald Trump's election campaign.

A Davis Polk spokeswoman declined to comment Wednesday about Andes' decision to join Mueller's team—his biography page no longer appears on Davis Polk's website—but a source at the firm confirmed Andres' departure.
