Congressman Chris Collins now faces fewer charges in his federal insider trading case. 

Federal prosecutors dropped three of the eight counts against Collins. He's still accused of insider trading, but dropping some of the more minor counts streamlines the case.

Prosecutors said their new indictment names fewer conspirators and makes the case simpler.  They hoped the trimmed-down indictment will help the case move smoothly the legal system without getting bogged down in appeals. 

Collins, his son Cameron, and Cameron's soon-to-be father-in law were indicted almost exactly a year ago. They're accused of selling off stock in an Australian biotechnology company because they had inside information it was going to tank and didn't want their stock to take a hit. 

Collins has pleaded not guilty and continues serving in the House of Representatives. His attorneys did not immediately respond to requests for comment.
