WASHINGTON, July 31 (Reuters) - The top U.S. derivatives regulator on Friday said it had ordered disgraced former Republican Congressman George Santos to pay $35,000 for alleged manipulative trading.

Santos, who was expelled from the House of Representatives in 2023, made nearly $18,000 by trading on prediction markets in February of this year that invited users to bet on whether he would personally attend President Donald Trump's State of the Union address, the Commodity Futures Trading Commission said in a statement.
