Scott O'Malia is resigning as a CFTC commissioner effective Aug. 8.
In a letter to President Barack Obama released by the Commodity Futures Trading Commission late Monday, Mr. O'Malia wrote that while he “found the position to be professionally fulfilling, I believe it is time to pursue other opportunities.”
“Although I did not support all 63 rules that the commission has implemented under Dodd-Frank, I am pleased to have contributed to the policy deliberations to improve commission rulemakings,” Mr. O'Malia, a Republican, wrote.
Mr. O'Malia was nominated to the CFTC by Mr. Obama in 2009. Prior to his appointment, he was staff director to the U.S. Senate Appropriations Subcommittee on Energy and Water Development, focusing on clean-energy technologies.
Mr. O'Malia's plans were not announced. Efforts to reach him were unsuccessful.
His replacement on the CFTC will be nominated by Mr. Obama and will require Senate confirmation.
