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.

Andres, 50, first joined Davis Polk as a litigation associate in 1997 before leaving the firm two years later for a position as an assistant U.S. attorney in the Eastern District of New York, where he spent nearly a decade based in Brooklyn. In 2010, Andres was named a deputy assistant attorney general of the U.S. Department of Justice’s criminal division, where he oversaw the fraud and appellate sections.

At Main Justice, Andres was heavily involved with policy and enforcement issues related to health care fraud and the Foreign Corrupt Practices Act (FCPA) and handled several high-profile trials including the prosecution of former Credit Suisse AG broker Eric Butler, who was convicted for his role in a $1 billion securities fraud scheme.

Andres re-joined Davis Polk in early 2012 as a partner in the firm’s litigation and white-collar criminal defense group in New York. He is also married to Ronnie Abrams, a sitting federal judge and daughter of legendary First Amendment lawyer and Cahill Gordon & Reindel senior counsel Floyd Abrams. Ronnie Abrams, a former pro bono counsel at Davis Polk, was appointed to the bench in 2012 after being nominated by the Obama administration. (She has since recused herself from two cases challenging Trump’s dealings with foreign governments.)

Since Mueller’s appointment more than two months ago, the former Wilmer partner has been stacking his legal team with current and former Big Law names. In June, Mueller added Wilmer partners James Quarles and Jeannie Rhee and former Jenner & Block partner Andrew Weissmann, an ex-chief of the Justice Department’s fraud section, to his investigations team.

Other individuals working for Mueller include criminal law specialist Michael Dreeben and appellate expert Elizabeth Prelogar—both of whom have worked at the U.S. solicitor general’s office—and Adam Jed from the Justice Department’s civil division.

Some of Mueller’s selections have come under fire from conservatives for their political donations to Democrats. Andres himself has contributed at least $3,700 to Democratic candidates. But others have noted that many prominent members of the Trump administration have a long history of giving to liberal politicians and causes.
