The race between Donald Trump and Joe Biden is on a knife edge, with no clear winner as vote-counting continues.
Results suggest a tight contest in important battlegrounds: Arizona, Georgia, Wisconsin, Michigan and Pennsylvania.
Trump is so far projected to win 23 states, including Texas, Ohio and must-win Florida, having outperformed pollsters’ predictions.
The President makes baseless claims of fraud and says he will launch a Supreme Court challenge even though millions of votes are still to be counted.
Biden could take Arizona, but is facing a much tougher fight than expected in Nevada. He says he is “on track to win”.
His campaign calls President’s Trump statement “outrageous”, adding: “The counting will not stop”.
The US is on course for its highest turnout in more than a century, and we might not have a result for days.
