Trump leads Biden in the potentially pivotal race of Florida with almost all votes counted. But other key states of Georgia, Pennsylvania, Wisconsin, Michigan, Arizona, Ohio, Texas, and North Carolina are toss-ups.

The vote caps a long and bitter race. More than 100 million people cast their ballots in early voting before election day on Tuesday - setting the US on course for its highest turnout in a century.

Control of Congress is also at stake. As well as the White House, Republicans are vying to hang on to a Senate majority.

The House of Representatives is expected to stay in Democratic hands.
