Romney and House Majority Leader Eric Cantor will be at Perelman's "The Creeks" estate for lunch, according to an invitation posted online by Politico. A spokeswoman for Perelman confirmed the invitation's authenticity. Donors who raise or contribute $25,000 can take part in a VIP photo reception at 12:30 p.m. A $5,000-per-person or $7,500-per-couple lunch is to follow.
At 5 p.m., Koch and his wife will host a dinner in their Meadow Lane home, according to an invitation posted on Buzzfeed. The suggested contribution is $50,000 per person or $75,000 per couple. A spokeswoman at Koch Industries did not immediately return an email Saturday seeking comment.
Former U.S. Ambassador Clifford Sobel will also host an event on Sunday, according to Politico.
"This is about the impact of money in politics. It's not about protesting Romney," coalition director Lisa Tyson said. "These donors are paying for influence. We want to make sure they know the 99 percent is watching."
Protesters plan to gather at Cooper's Beach in Southampton at 3:30 p.m., marching to Koch's estate at 4, Tyson said.
A statement from Koch's representatives posted Saturday on KochFacts.com called it hypocritical for liberals to assail money in politics given Obama's prodigious fundraising.
"The message from the Left is that fundraising for their preferred candidates is fine, but donations to those with differing points of view are somehow immoral," the statement said.
