Trump announced Friday the swearing-in would move from the Capitol steps, where risers and a huge stage had already been erected, into the Capitol rotunda given expected subfreezing temperatures.

In the early afternoon, Mr. Trump is scheduled to hold a campaign-style rally at Capital One Arena, blocks from the National Mall, his first such address in Washington, D.C., since the election in November. The president-elect will end his day by attending a candlelight dinner with supporters.

President-elect Donald Trump took a victory lap on Sunday night, telling his supporters at a campaign-style rally that his first day in office will come with a flurry of executive orders to fulfill his 2024 campaign promises.
