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.

On the eve of his scaled-down second inauguration, President-elect Donald Trump vowed to quickly close the southern border, deport millions of undocumented immigrants and sign a litany of other executive orders when he returns to power on Monday.
