RCP got its hands on an invitation to a Republican National Committee fundraiser scheduled for next week in Las Vegas, with embattled Sen. John Ensign (R-Nev.) listed as one of the "special guests."

The "Sun & Fun In The Desert" event was scheduled for October 16-18 at the Palazzo Resort Hotel Casino. Also listed as special guests were RNC co-chairman Jan Larimer, and Rep. Dean Heller (R). The invitation, which was received just last week, sought contributions from PACs of $5,000 to $15,000.

When asked about the event, a spokesperson for the RNC first said that Larimer may not attend, then later said the event itself may have been canceled. Sure enough, a Palazzo employee said the event was taken off their schedule just today. An Ensign spokesperson referred calls to the RNC. Further requests for comment from the RNC, as well as requests to the Nevada GOP and Heller's office have not been returned.

The cancellation of this event comes as leading Republicans have sought to distance themselves from Ensign, once rumored as a potential White House candidate but now facing calls to resign over alleged impropriety stemming from an affair with a former staffer.
