Willkie Farr & Gallagher staffed up its Washington, D.C., office with two high-ranking federal government lawyers this week.

Norman Bay, the former U.S. attorney for New Mexico and most recently chairman of the Federal Energy Regulatory Commission, and Priya Aiyar, previously the Treasury Department's acting general counsel, joined Willkie as partners Tuesday. Bay will lead the firm's energy regulatory and enforcement group, the firm said.

While their practices are unrelated, the two new partners help to build out the elite New York firm's regulatory capabilities in Washington.
