More than 500 people have registered to attend a Hamptons fundraiser for President Trump at real estate developer Joe Farrell’s home on Friday, with 300 people paying to attend the after-party.

Both events will be held at the Sandcastle mansion in Bridgehampton, which is currently on the market for $39.99 million via Bespoke Real Estate and where stars including Beyoncé and Jay-Z have summered.

Friday’s guests include Treasury Secretary Steven Mnuchin, Commerce Secretary Wilbur Ross, Donald Trump Jr. and his girlfriend Kimberly Guilfoyle. “We’ve raised more than $4 million so far,” Farrell tells Gimme Shelter.
