US President Donald Trump and his Democratic challenger Joe Biden have spent the final hours of the White House race delivering their closing pitch to voters in critical states.

Mr Biden campaigned in Pennsylvania and Ohio, as Mr Trump toured the voting battlegrounds of Wisconsin, Michigan, North Carolina and Pennsylvania.

More than 98 million people have already cast their ballots in early voting, putting the country on course for its highest turnout in a century.

In the US election, voters decide state-level contests rather than an overall single national one.

To be elected president, a candidate must win at least 270 votes in what is called the electoral college.

Each US state gets a certain number of votes partly based on its population and there are a total of 538 up for grabs.

Tuesday’s vote comes amid the ongoing coronavirus pandemic.

Where are Biden and Trump on campaign’s final day?

After North Carolina, Mr Trump headed to Scranton, Pennsylvania, the city where his opponent lived until he was 10.

On Monday, Mr Trump also held rallies in Traverse City, Michigan, and Kenosha, Wisconsin. Kenosha was rocked by violent protests in August after the police shooting of a black man.

In Traverse City he asked for the votes of black Americans, BBC reported.
