Former US Rep. Chris Collins arrived at Manhattan federal court Tuesday afternoon to plead guilty to insider trading charges.

The disgraced Republican’s appearance came mere hours after his resignation letter was read aloud on the House floor.

Collins was charged with insider trading in 2018, after he called his son Cameron from a congressional picnic to pass along information about a failed drug trial, prompting the son to dump stocks.

Outside court, he even told reporters he wasn’t yet sure if he’d run again — but bragged that he’d win again if he did.

Cameron and a co-defendant are expected to enter a guilty plea Thursday.
