The Commodity Futures Trading Commission, which regulates derivatives markets, did not respond to several requests for comment.

On Thursday, a group of congressional Democrats introduced a bill that that would ban bets on elections, government actions, war and sports, CNBC reported. Even some members of Trump’s own party are seeking clarity on the trades.

“Someone needs to be publicly shamed for insider trading,” said Republican Jeremy Munson, a candidate for the Minnesota Senate.

Mark Neuman, chief investment officer at Hero Asset Management, said it should be possible to discover the identities of those who placed the trades in question, and suggested the problem resulted more from lax oversight.

“When you make a transaction, there are details you have to provide” to the exchanges, “so there’s no secret,” Neuman said. “If there were stricter regulators in this country, we would find out” their identities.

“But it seems this administration favors less regulation,” he said. “It’s really sad, because the integrity of the markets is being torn to shreds.”
