As news swirls in Washington, D.C., over the latest scandal to hit the Trump administration, the central figure in the scandal of the past—the Russia investigation—has melted back into his partnership at Wilmer Cutler Pickering Hale and Dorr.

Robert Mueller left the firm in 2017 when he was appointed special counsel to investigate Russian interference in the 2016 election. Two other attorneys who worked alongside Mueller in the special counsel’s office, Aaron Zebley and James Quarles, have also migrated back to Wilmer as partners along with Mueller.
