US election 2016 live: Donald Trump campaign launches lawsuit claiming voting fraud in Nevada as Hillary Clinton up three points in race to become America’s next president

A divided nation is picking its next president today, amid concerns of potential voter intimidation and accusations by Donald Trump of rigged polls.

Final exit polls from Fox News gave Mrs Clinton a four-point lead, while Reuters stated she had a 90 per cent chance of victory.

Mr Trump voted on Tuesday at around 11am in Manhattan, arriving at the polling station to boos and cheers accompanied by his wife Melania and daughter Ivanka.

But before voting, he told Fox News that he thought the polls, which show Hillary Clinton with a narrow victory, were intentionally wrong.

“I do think a lot of the polls are purposely wrong,” he said.

He predicted wins in the battleground states of Iowa and New Hampshire, but ultimately said: “Who knows what’s going to happen?”

The Trump campaign launched a lawsuit alleging voter fraud in Nevada. There were also technical issues in some North Carolina precincts meaning paper ballots were being used.

At around 8am Hillary Clinton had voted with her husband in Chappaqua, New York.

She said she was “humbled” by the process.

“It is the most humbling feeling because I know how much responsibility goes with this and so many people are counting on the outcome of this election,” she said.

“I know how much responsibility is on it, what it means for this country and I’ll do the very best that I can if I’m fortunate enough to win today.”
