The U.S. Securities and Exchange Commission's chief of staff plans to leave the agency in early August for private law practice.
Lucas Moskowitz, who has spent two years as the top aide to SEC Chairman Jay Clayton, will become a partner at the WilmerHale law firm in Washington.
Moskowitz's job at the SEC has put him at the center of much of the agency's business, including policy making, enforcement actions and personnel decisions. He's also been a key person in the regulator's dealings with Congress and other agencies.
"He is one of those people who makes the hard things look easy," Clayton said in an interview. "All of a sudden you look up and the problem's solved."
