Sen. Dean Heller has been a proud fan of the Las Vegas Golden Knights' historic season, hanging a team banner in his office and personally attending the team's Game 4 loss to the Washington Capitals last week.

But Heller, who chatted with sports reporters ahead of the game in the nation's capital, was also there for another reason — fundraising.

An invitation obtained by The Nevada Independent shows that Heller's leadership PAC, HellerHighWater PAC, held a fundraising event at the game in conjunction with a PAC affiliated with health insurance giant Blue Cross Blue Shield.

The listed entry price to attend the fundraiser and hockey game was $3,000 for one ticket or $5,000 for two. According to TicketIQ.com, the average secondary market price of a ticket to Game 4 was $1,558.

Holding campaign events at a sporting event isn't unusual — CNN reported that political campaigns, candidates and PACs spent $432,000 on fundraising events between 2005 and 2010 at Washington Nationals games.

Heller has reported receiving $14,000 from Blue Cross Blue Shield since 2013, according to a tally by the Center for Responsible Politics. Notably, the insurance company opposed a health insurance overhaul plan by Heller and Republican senators Lindsay Graham and Bill Cassidy, saying it would "increase uncertainty in the marketplace, making coverage more expensive and jeopardizing Americans' choice of health plans."
