As a bitter and divisive US election campaign draws to a close, the world is watching and waiting for the results.
RTÉ News will have comprehensive coverage online, and on radio, television and social media, as the results come in over the coming days.
Democratic challenger Joe Biden has kept a relatively steady lead in national polls, but Donald Trump, the Republican incumbent, is close in enough swing states to have a chance of piecing together the 270 state-by-state Electoral College votes needed to win the presidency.
With more than 98 million early votes already cast in person or by mail as of Monday night, a number equal to about 71.4% of the entire turnout in 2016, experts have been at pains to warn that early results can be misleading, as mail-in ballots can take longer to count.
RTÉ News will have comprehensive coverage and expert analysis of the results as they come in.
A dedicated section of the RTÉ News website is already replete with stories and analysis from the campaign trail. A live blog with the latest results and news from the election will run through the night.
You can also follow developments on Facebook, Twitter and Instagram. You can follow RTÉ Washington Correspondent Brian O'Donovan on Twitter for the latest updates direct from the US.
