Voting is over the United States election for President and other elected representatives. Counting is underway in most states and some of the smaller states have declared winners. However in other states it will take much longer to count all the votes and declare a winner.
The US Presidential election is decided by an electoral college system where each state has a set number of votes in the electoral college depending on the population of the state. To win the Presidency the candidate has to each 270 electoral college votes. At 10am SA time Joe Biden had 230 electoral college votes and Donald Trump has 213. However there are still many states to declare, and Donald Trump is ahead in a number of those states.
The President made a speech to supporters from the White House at 2:30am, noting that it was the latest he'd ever given a live speech. He complained that he was on the way to a historic win and was all set to celebrate before, "It all stopped". He seemed to be referring to certain states where counting stopped. This is normally done because it is very late in the morning and the counters start again the next day when they are fresh.
Trump claimed that he was the winner of the election and that he would be going to the US Supreme Court to stop the counting at states where he is not winning.
