President-elect Donald Trump is set to be inaugurated Monday, amid a day of traditions marking the transfer of power that’s expected to be attended by three former presidents and several billionaires.

Trump’s swearing-in will take place at noon. It will be carried live by most TV networks and streamed by the White House. More details on the schedule are available here.

Outgoing President Joe Biden will attend the ceremony, along with former Presidents Barack Obama, George W. Bush and Bill Clinton.

Beyond members of Trump’s family and administration, a litany of political heavyweights usually attend the swearing-in. This year, a handful of tech industry titans are also expected to attend, including billionaires Elon Musk, Mark Zuckerberg, Jeff Bezos and Sam Altman, along with TikTok CEO Shou Zi Chew. Country singer Carrie Underwood is scheduled to perform “America the Beautiful,” one of several artists who’s slated to participate (here’s a full list).

Supreme Court Chief Justice John Roberts will administer the presidential oath to Trump, and Justice Brett Kavanaugh will administer the oath to Vice President-elect JD Vance.

Neither are expected to attend. Michelle Obama’s office cited a scheduling conflict, and Pelosi’s office did not give an official reason, but the former House Speaker and Trump have a long-running feud.

The three-day event officially began Sunday with a wreath laying ceremony at the Tomb of the Unknown Soldier at Arlington National Cemetery, followed by a “victory rally” at Capitol One Arena in Washington. A National Prayer Service will conclude the official inaugural events Tuesday.
