The world’s three wealthiest people are expected to pop up in Washington, D.C., for Donald Trump’s inauguration and surrounding events—joining a long list of other billionaire attendees.

Real estate investor Steve Witkoff is the chair of the inauguration, which was moved inside the Capital Rotunda, where a smaller crowd will huddle away from freezing temperatures outside, the New York Times reported. The roster of confirmed attendees is already a veritable who’s who in real estate and tech.
