US presidential elections: Voting underway
According to reports, polls opened at 6:00 am (local time) on the East Coast.
On the other hand, three New Hampshire villages cast their votes after midnight.
The CNN Poll of Polls shows Clinton leading by four points.
After polling ends on the West Coast, results are expected to emerge toward midnight, reports said.
Both the candidates tried to reach out to as many voters as possible on the last day of campaigning for the polls on Monday.
Clinton and Trump hold rallies in crucial states like North Carolina, Pennsylvania and Michigan.
"Tomorrow, we face the test of our time. What will we vote for?" Clinton tweeted.
"I am not going to let anybody rip up the progress that we’ve made," she said.
Urging voters to vote in her favour, Clinton said: "Let’s make history!”
The FBI has said that there is no case against Democratic presidential nominee Hillary Clinton regarding the new batch of emails linked to her private email server, the media reported on Monday.
According to media reports, FBI director James Comey told congressional leaders in a letter on Sunday that the agency reiterates its conclusion that no criminal wrongdoing has been involved.
Clinton's rival, Donald Trump, the Republican nominee for the presidential elections to be held on Nov 8, has accused the FBI of impropriety after the agency exonerated Hillary Clinton, according to media reports.
Her rival Trump attended five rallies on Monday.
Attending the rallies, he attempted to reach every last voter and bring votes in his favour.
"Unbelievable evening in New Hampshire - THANK YOU! Flying to Grand Rapids, Michigan now," read his last tweet.
Trump is facing the heat following allegations of sexual misconduct made against him.
Donald Trump urged voters on Sunday to "deliver justice at the ballot box" on Election Day.
An election for President of the United States occurs every four years on Election Day, held the first Tuesday after the first Monday in November.
The election process begins with the primary elections and caucuses and moves to nominating conventions, during which political parties each select a nominee to unite behind.
The nominee also announces a Vice Presidential running mate at this time.
The candidates then campaigned across the country to explain their views and plans to voters and participate in debates with candidates from other parties.
During the general election, Americans head to the polls to cast their vote for President. But the tally of those votes—the popular vote—does not determine the winner. Instead, Presidential elections use the Electoral College.
To win the election, a candidate must receive a majority of electoral votes.
In the event no candidate receives the majority, the House of Representatives chooses the President and the Senate chooses the Vice President.
A candidate needs the vote of at least 270 electors—more than half—to win the Presidential election.
