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.

The campaign-style rally was a break with tradition for presidents, who have sought to reserve their comments for the official inauguration speech.

On the eve of his inauguration, President-elect Donald Trump energized his supporters, laying out the goals of his second administration, thanking the allies that helped him achieve his victory, while giving hints at the legislative agenda he is going to immediately seek to achieve.

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.
