The new indictment against Collins streamlines the charges against the lawmaker by keeping only five of the original eight securities fraud counts from the original indictment.
The new indictment also drops two of the original eight securities fraud charges against the congressman's son, Cameron Collins, while leaving the remaining charges in place.
They say the son traded on the inside information and passed it to Zarsky.
When asked about the report by Fox News, Collins at the time called Slaughter “a despicable human being.” Collins disputed the findings and said he has “always followed ethics.”
Following the charges brought against Collins last year, then-House Speaker Paul Ryan removed Collins from his post on the House Energy and Commerce Committee and called the insider trading charges "a clear violation of the public trust."
