The son of former congressman Chris Collins pleaded guilty Thursday in an insider trading case.

Cameron Collins admitted in federal court in Manhattan that he had traded stocks based on an illegal tip from the then-congressman.

Earlier this week, Chris Collins pleaded guilty to securities fraud conspiracy and making false statements to the FBI. He also resigned from Congress.

The case against Collins stemmed from his business dealings with Innate Immunotherapeutics, a biotech company based in Australia.

Collins was the company's largest shareholder and sat on its board.

He received an email from the company that a drug developed to treat multiple sclerosis had proven to be a clinical failure. He then called his son with the information.

Cameron is accused of tipping off his future father-in-law, Stephen Zarsky, who was also in court Thursday.

Cameron faces up to 46 months in prison when he's sentenced in January.
