Mega-dealer Larry Gagosian will host a fundraising auction for Hillary Clinton on September 12 in his New York City gallery. According to Artnews, the private event will include works by Jeff Koons, Sarah Sze, Chuck Close, and Barbara Kruger. This will be the first fundraising event that Gagosian has organized for a presidential candidate, though he has made donations to a number of political campaigns, including those of Chris Christie, John Kerry, and Mitt Romney.
