Vice President Joe Biden and his wife, Dr. Jill Biden, landed in the Hamptons Friday for a family vacation with lesbian, gay, bisexual, transgender-rights activist David Bohnett. The Bidens are staying at Bohnett’s home in the estate section of Southampton. According to the White House, Bohnett, who’s made large contributions to the Democratic National Committee, is a family friend of the Bidens. He founded GeoCities in 1994 and is chairman of the David Bohnett Foundation, a nonprofit aimed at “improving society through social activism.”
