The White House has withdrawn Brian Quintenz’s nomination to serve as a board member and chair of the Commodity Futures Trading Commission (CFTC). Politico reported on Tuesday, citing two sources who spoke on condition of anonymity ahead of an official announcement.  “Being nominated to chair the CFTC and going through the confirmation process was the honor of my life,” Quintenz said. “I am grateful to the President for that opportunity and to the Senate Agriculture Committee for its consideration. I look forward to returning to my private sector endeavors during this exciting time for innovation in our country.”
