Republican presidential candidate and former Massachusetts Gov. Mitt Romney is scheduled to make a brief trip to the Vineyard Saturday for a private fundraising event.

Mr. Romney has no public appearances planned during his visit.

The event is a clambake luncheon at the Oak Bluffs home of Kate and Jim Sims in Farm Neck.

According to an invitation to the event sent to the Gazette, there will be an 11 a.m. VIP reception for those who contribute or raise $50,000 per person, and an 11:30 a.m. photo reception for those who raise $25,000 or contribute $10,000 per person. A general reception, planned for noon, requires a contribution of $2,500.

Resort casual attire is requested.

Representatives from Mr. Romney’s campaign did not respond to requests from the Gazette for more information about the event and Mr. Romney’s schedule.

Jim Powell, chairman of the West Tisbury Republican town committee, said that after attending the Vineyard event, Mr. Romney would attend fundraisers in Osterville and Nantucket.

After vacationing on the Vineyard for the past two summers, President Barack Obama has no plans to come to the Island this year. But fundraisers are being held on his behalf, including a fundraiser earlier this week featuring cast members from the television show The Wire at the Davenport home in Oak Bluffs.
