The White House withdrew former Commodity Futures Trading Commissioner Brian Quintenz's nomination to run the agency late Tuesday, capping off a month-long fight over U.S. President Donald Trump's pick for agency chair. Trump tapped Quintenz shortly after retaking office. Quintenz joined venture firm Andresseen Horowitz's global head of policy, and has been an adviser to firms like prediction marketplace Kalshi since leaving the CFTC following his term as commissioner.
