First daughter Ivanka Trump and her husband Jared Kushner were spotted at a party over the weekend rubbing elbows with billionaire Democratic financier George Soros and Senate Minority Leader Charles Schumer (D-N.Y.), Politico reported Sunday.

The couple were among the guests at Lally Weymouth’s Southampton home Saturday, where the former Washington Post editor — whose family owned the newspaper for decades — was holding a star-studded annual party.

Kushner and Trump are both advisers to President Trump. Soros, a major donor to Democratic causes and an ardent opponent of Trump, has been accused by a number of Republicans of funding anti-Trump protesters.

Other guests at the party included White House senior counselor Kellyanne Conway, Rep. Lee Zeldin (R-N.Y.), former New York City police commissioner Bill Bratton and business mogul and longtime Trump friend Carl Icahn, according to Politico.

GOP donor David Koch also attended the party.

Weymouth's brother, former Washington Post publisher Don Graham, reportedly made a speech about Weymouth’s birthday Monday and touted the upcoming Steven Spielberg film on the Post’s publication of the Pentagon Papers. The director also attended the party.
