Jeff Bezos opened the doors to his fancy mansion in Washington, D.C., over the weekend for an after-party that featured a who’s who of the Capital political scene as well as such notable guests as Microsoft co-founder Bill Gates and actor Ben Stiller.

According to reports in Politico, the Daily Mail and elsewhere, Bezos’ bash at his $23 million home in D.C.’s fancy Kalorama district Saturday night followed the exclusive Alfalfa Club Dinner. The social club for the rich and famous and well-connected apparently holds one dinner per year.

The guests in fancy gowns and tuxedos included notable White House personalities such as Ivanka Trump, Jared Kushner and Kellyanne Conway, according to Politico. Fellow tech billionaire Gates was also photographed by the Daily Mail, wearing the Alfalfa Club’s signature gold medallion around his neck, as was Sen. Mitt Romney. JP Morgan Chase CEO Jamie Dimon and Amazon PR and policy chief Jay Carney were also on the guest list Politico shared.

Romney was the keynote speaker at the dinner and Politico offered up one of his “top lines”: “Everyone’s worried about artificial intelligence and robots taking over the world. That’s not true or I would be president now.”

Bezos, who owns The Washington Post, reportedly hosted with girlfriend Lauren Sanchez but the pair were not photographed. Bezos bought the 27,000-square-foot former Textile Museum in October 2016. The property boasts 11 bedrooms and 25 bathrooms and went through what was reported to be a $12 million renovation. The Kalorama neighborhood is also home to President Barack Obama and Ivanka Trump and Kushner.

The party came after a week of revelations related to the alleged hacking of Bezos’s phone by Saudi crown prince Mohammed bin Salman. The Wall Street Journal reported on Friday that federal prosecutors have evidence indicating Sanchez provided text messages to her brother that were eventually sold to the National Enquirer for an article about Bezos and his affair at the time.
