Former New York Republican Rep. George Santos on Wednesday challenged an NPR report that the Department of Justice is investigating him for allegedly benefiting from insider trading on the Kalshi prediction market.

Santos is alleged to have placed bets on his attendance at the president’s State of the Union address in February, according to NPR. Santos initially said he would personally attend the event — he was expelled from Congress in December 2023 — but he ended up watching President Donald Trump’s speech from an airport instead.
