The Department of Justice and Commodity Futures Trading Commission are investigating former U.S. Rep. George Santos after Kalshi detected suspicious trades tied to his attendance at President Trump's February State of the Union address, froze his account and referred the matter to regulators, according to NPR.

NPR said Santos allegedly made tens of thousands of dollars betting that he would not attend after posting a video on X saying he would be in the gallery. He later posted from an airport as President Trump spoke, and the odds on his attendance plunged.

Kalshi has requested to interview Santos as part of its investigation, according to a person familiar with the matter. He has dodged those requests, that person told NPR.

Reached by NPR, Santos said, "Well, that's news to me."

The Block has reached out to the DOJ, the CFTC, Kalshi, and Santos for comment.
