CBS News has posted a video where they claim New York Representative Chris Collins is talking to his son about failed drug testing that led to his arrest for insider trading.

Collins, who is a Republican congressman from New York, was arrested yesterday and charged with being a part of an insider-trading scheme. He is accused of selling the shares of an Australian biotechnology company before the public disclosure of a failed drug trial.

Collins went to Twitter to deny the charges.

Collins pleaded Not Guilty in court on Wednesday.
