Former Cravath Swaine & Moore corporate partner Timothy Massad was sworn in Thursday as chairman of the U.S. Commodity Futures Trading Commission.

Confirmed by the U.S. Senate on June 3 via voice vote, Massad most recently oversaw the Troubled Asset Relief Program at the Treasury Department. He replaces Gary Gensler, who stepped down at the end of 2013. Mark Wetjen had been serving as acting chairman in the interim.

The Senate on Tuesday also confirmed Latham & Watkins securities partner Sharon Bowen to fill a commissioner slot left vacant when Democrat Bart Chilton departed in March. He joined DLA Piper’s Washington office as a senior policy advisor in April.

J. Christopher Giancarlo, executive vice president at interdealer broker GFI Group Inc., was also confirmed as a commissioner, filling the seat last held by Republican Jill Sommers.
