Cheramy pleaded guilty to insider trading and was ordered to pay a $250,000 fine, according to the Wyoming newspaper. He also served three years of probation and did 500 hours of community service.
"I've moved on beyond all of that stuff," Cheramy told the Star-Tribune.
Enzi's campaign did not comment to the Wyoming paper.
After IDB, Cheramy served as a volunteer at the Jackson Hole Wildlife Foundation, the Community Foundation of Jackson Hole and the Jackson Hole Community Housing Trust. The Republican National Committee also held at party at Cheramy's house roughly two years ago.
