Democratic candidate Kamala Harris and her Republican rival, Donald Trump, are vying for the presidency of the United States.
So far, the two candidates have been projected to win a number of states they were expected to carry, but battleground states remain too close to call.
Polls have started closing in parts of the country, while voting in the November 5 election continues largely smoothly across the rest of the US.
Pre-Election Day surveys showed the two candidates in a tight race nationally and in seven swing states: Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania and Wisconsin.
To win the presidency, a candidate needs at least 270 Electoral votes.
