US President Donald Trump and rival Joe Biden are travelling across the US as the election enters its closing stage.
Trump planned to visit five battleground states while his challenger Biden spoke at a campaign event in Pennsylvania.

More than 90 million people have already cast their ballots in early voting, putting the country on course for its highest turnout in a century.
