By Steve Holland and Tim Reid WASHINGTON (Reuters) -Thousands of Donald Trump's supporters packed a Washington arena on Sunday to celebrate his victory, a day before the president-elect returns to power with plans to aggressively reshape U.

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.
