Now, Matthew Petraca, the lead federal prosecutor on the case, has stepped aside, according to a court filing.

It shows he has been replaced.

It didn't explain why.

Comey says his post wasn't a call to violence, saying to him, 86 was an expression of wanting to be done with something.

Comey's lawyers have said they intend to file a vindictive prosecution motion.

Prosecutors have unsealed an indictment against Gannon Ken Van Dyke, a U.S.

Special Forces soldier who helped plan and carry out the arrest of Maduro.

Under the username BurdensomeMix, Van Dyke allegedly placed $32,000 in bets on Polymarket that Maduro would soon be out of power.

Those wagers netted him more than $400,000 in profit.

Polymarket is an overseas, unregulated exchange where traders are anonymous and bet with cryptocurrency.

But federal investigators worked with Polymarket to identify Van Dyke.

He's the first person criminally charged in the U.S.

over trades on prediction markets, which have seen massive growth in Trump's second term.

Donald Trump Jr.

is an investor and advisor to Polymarket.

Polymarket bettors earned hundreds of thousands of dollars on the timing of military strikes in Iran and when Venezuelan leader Nicolás Maduro was captured.

Now, prosecutors in the Southern District of New York are investigating the trades.

CNN first reported the probe.
