WASHINGTON -- The Latest on Election Day 2016 (all times EST):
5:20 p.m.
Neither Donald Trump nor Hillary Clinton is able to claim favourable standing with a majority of the U.S. electorate.
Six of 10 voters say they are somewhat bothered or bothered a lot by Clinton's use of a private email server while secretary of state, according to preliminary results from exit polling conducted by Edison Research for The Associated Press and television networks.
More than seven out of 10 presidential voters say they are irked by Trump's treatment of women.
Trump hammered Clinton for how she handled classified information at the State Department. The FBI twice said it had no cause to pursue criminal charges.
Clinton blistered Trump after disclosure of a 2005 video that captured Trump discussing sexually predatory behaviour toward women.

5:10 p.m.
Fewer than half of voters who cast presidential ballots say they made their choice out of a strong preference for their candidate.
That's according to preliminary results of the exit poll conducted for The Associated Press and television networks by Edison Research.
The early exit polls found both Republican Donald Trump and Democrat Hillary Clinton are viewed unfavourably by a majority of the presidential electorate. A majority of the electorate also distrusts each of them.
A third of voters said they have reservations about the candidate they backed. A quarter of voters say their vote was mostly about opposing another candidate.
In 2012, the presidential electorate was more optimistic about their choices. That year, about two out of three voters said they strongly backed their candidate.

5:05 p.m.
Seven in 10 Americans going to the polls Tuesday say they think immigrants now in the country illegally should be allowed to stay. Just a quarter say they should be deported.
More than half say they oppose building a wall along the Mexican border to stop illegal immigration, according to preliminary results from the exit poll conducted for The Associated Press and television networks by Edison Research.
But immigration isn't necessarily at the top of the minds of most voters. Just 1 in 10 say immigration is the most important issue facing the country.
Republican Donald Trump made cracking down on immigration a top item on his agenda.

5 p.m.
Most voters going to the polls Tuesday have a pessimistic view of the U.S. economy.
According to preliminary results of an exit poll conducted by the Associated Press and television networks by Edison Research, about 6 in 10 describe the state of the economy as not so good or poor.
But that economic unhappiness isn't as high as it was in 2012, when three-quarters called the economy not so good or poor.
Among voters today, 3 in 10 say their personal financial situation has gotten better in the last four years, while nearly as many say it's gotten worse.
More than half of voters say the economy is the most important issue facing the country, over terrorism, foreign policy and immigration.

4:50 p.m.
Authorities have beefed up Election Day security for Donald Trump by parking dump trucks filled with sand outside his Trump Tower building on Fifth Avenue.
Police said Tuesday that similar precautionary measures were being taken at other sites around midtown Manhattan where Trump and Hillary Clinton plan to spend election night.
Authorities say the heavy trucks could block an attempted car bombing. They say there are no confirmed terror threats.
The NYPD had previously said it will deploy more than 5,000 police officers to keep order on election night. The deployment also includes police helicopters, mobile radiation detectors and bomb-sniffing dogs.

4:40 p.m.
A state judge in Nevada has denied a request from the Donald Trump campaign to preserve ballots and voting materials related to what the campaign alleges were irregularities during early voting.
Clark County District Court Judge Gloria Sturman said Tuesday that making the names of poll workers part of the court record could expose them to "public attention, ridicule and harassment."
She says the county registrar is already required to keep the records, and the Nevada Secretary of State is responsible for investigating the complaint.
Trump campaign attorney Brian Hardy told the judge he wants to preserve records from the final day of early voting at four locations in the Las Vegas area.
The campaign says allowing people to vote past closing time was illegal, but the county says they were accommodating people already in line.
The Trump campaign lodged a separate complaint with the secretary of state.

4 p.m.
A software glitch that indicated scores of voters showing up at the polls had already cast ballots has led to voting delays in one of North Carolina's most heavily Democratic counties.
North Carolina Board of Elections lawyer Josh Lawson says officials in Durham County quickly concluded that there was a problem with their electronic poll books and began relying on paper rolls to confirm voter registrations. Attempts to vote twice are rare.
Lawson says there's no indication "nefarious activity" caused the computer problems. Rather, he said it could have been a failure to clear out caches of votes cast during the primaries.
About two dozen other counties using the same software have not reported problems.
Lawson said those in line when the polls close will still be allowed to vote.

3 p.m.
President Barack Obama is hitting the radio airwaves to encourage Americans to go to the polls to vote for Hillary Clinton.
The White House said Obama gave Election Day interviews to six radio stations that target listeners in Orlando, Detroit and Philadelphia. The cities are in states where the race is believed to be close between Clinton and Republican Donald Trump.
Obama told syndicated host Jana Sutter that continuing the work of the past eight years depends on having a "steady, smart, serious" president follow him into office.
He praised Clinton and reiterated his view that Trump is unfit to be president.

2:45 p.m.
Donald Trump is rekindling his unsubstantiated concerns about a rigged election system.
Asked Tuesday afternoon on Fox News if he would accept the election results, Trump continued to demur.
The Republican presidential nominee said: "We're going to see how things play out."
He said. "I want to see everything honest."
Concerns about voter intimidation and fraud led to a flurry of lawsuits in the run-up to Election Day. New voter regulations in more than a dozen states also held the potential to sow confusion at polling places.
But at least in the early going, most of the problems at polling places appeared to be routine -- the kinds of snags that come every four years, including long lines, machines not working properly, and issues with ballots or voter rolls.
------
2:20 p.m.
It could be the first lawsuit of Election Day. Donald Trump's campaign is alleging polling place "anomalies" during early voting in the Las Vegas area last week.
A lawsuit filed Tuesday in Nevada court asks that records from four early voting spots that allegedly stayed open too late last Friday be impounded and preserved.
Long lines kept polls open past the 7 p.m. posted closing time at locations that included a Mexican market and several shopping centres. Officials say at one site, the last voter cast a ballot after 10 p.m.
Criticism is also coming from state Republican Party chief Michael McDonald.
But Democrat Hillary Clinton's campaign is dismissing the Nevada case in a Twitter message, calling it "a frivolous lawsuit."

1:30 p.m.
President Barack Obama says his faith in the American people hasn't wavered.
Asked whether he was feeling nervous about the presidential election outcome, Obama said "I think we'll do a good job" as long as the American people vote.
Lines were long in some areas as voters chose between Democrat Hillary Clinton, Republican Donald Trump and some third-party candidates.
Obama said he hopes everyone has "voted early. If not, get out there."
Obama supports Clinton and voted early last month in his Chicago hometown. He spoke while walking from the White House residence to the Oval Office, following his Election Day tradition of playing basketball with friends.

1:25 p.m.
Eric Trump may have broken New York state law by tweeting a photo of his completed ballot.
The second son of Republican presidential candidate Donald Trump tweeted a photo of a ballot with the oval over his father's name filled in on Tuesday.
The tweet said "It is an incredible honour to vote for my father! He will do such a great job for the U.S.A!" It was later deleted from Trump's Twitter account.
An 1890 New York law bans voters from showing marked election ballots to others. A federal judge ruled last week that the law applies to social media posts.
Representatives for Eric Trump and the New York City Board of Elections did not immediately respond to calls seeking comment.

1:20 p.m.
It was a quick trip to the voting booth for Donald Trump's running mate on Tuesday.
Indiana Governor Mike Pence was joined by his wife, Karen, as they voted in Indianapolis. The couple encountered no lines and spent about five minutes filling out their ballots.
Pence told a small crowd afterward that he was grateful for the "support and prayers of people all across the United States" and he pledged a more prosperous America with the Trump-Pence ticket.
Pence and his wife voted in a precinct that has leaned liberal in past elections.

1:15 p.m.
Norwegian Prime Minister Erna Solberg says a victory for Hillary Clinton on Election Day would be "inspirational" to young women. But she joked that this wouldn't lead to a "global girlfriends' network."
At a Berlin press conference with German Chancellor Angela Merkel Tuesday, Solberg said a female U.S. president would show women that politics isn't "something that belongs to men."
Merkel echoed Solberg's comments about creating more of a global balance between men and women in power. She declined to comment on whom she'd like to win the election, pointing out that the "trans-Atlantic partnership is certainly a prerequisite for us, especially co-operation in NATO."
Republican Donald Trump has said that he may revisit the longstanding NATO alliance if elected.

12 p.m.
Billionaire Warren Buffett is devoting part of Election Day to get-out-the-vote efforts -- as he helps drive voters to the polls on a trolley he hired.
The longtime Democrat had promised to help boost turnout at a Hillary Clinton rally in Omaha in August. Buffett says some people have it tougher than others -- maybe an illness or trouble with their car. He says he wants to do his part so everyone gets a chance to vote.
More than 1,000 people have volunteered to help Buffett drive voters to the polls.
Buffett is a supporter of Clinton's, but on Tuesday he declined to talk about that. Instead, he said he just wanted to encourage everyone to vote regardless of party affiliation.

11:40 a.m.
President Barack Obama says on Twitter that "progress is on the ballot" Tuesday.
He's urging his more than 11 million Twitter followers to "go vote." He also says they should make sure that their friends, family and everyone they know votes, too.

He used the "progress is on the ballot" line at many of the get-out-the-vote rallies he headlined for his former secretary of state.

11:35 a.m.
Election officials say voting machine problems in southern Utah are forcing poll workers to use paper ballots, potentially affecting tens of thousands of people.
Utah Director of Elections Mark Thomas says a programming problem has affected all voting in Washington County, but so far appears it appears limited to that county.
He says about 52,000 registered voters there have yet to cast their ballots.
Election workers are trying to fix the computer problem and hope they can start using the voting machines later in the day.
Thomas says officials were prepared with backup paper ballots. But he said they will need to print more if the problem persists.
There are about 80,000 total registered voters in Washington County. Some 28,000 have already cast their ballots through early voting.

Donald Trump has voted in New York City.
Hundreds of onlookers watched as Trump, his wife Melania, daughter Ivanka, and son-in-law Jared arrived Tuesday morning at their polling place at a public school on Manhattan's East Side.
Trump said: "it's a great honour, a tremendous honour" to be casting his ballot.
He said he's feeling confident about the outcome, citing "tremendous enthusiasm."
As for his longstanding concerns about voter fraud, he says. "We're always concerned about that."
His final message to voters: "Make America great again. That's all it is. That's what it's all about."

11:05 a.m.
Hillary Clinton is getting some quirky questions in Election Day radio interviews.
Clinton phoned WKZL in North Carolina and was asked whether she prefers Pepsi or Coke? Coke, said Clinton.
Toilet paper -- over the top or under the bottom of the roll? "Usually over, but I can live with under," quipped Clinton.
And, sleeping arrangements. Clinton told WXKS in Boston that she won't switch which side of the bed she sleeps on if elected president. The White House will have to put the storied presidential phone on her side, not on the side that her former president husband sleeps on.
She said: "I have my side, and it works very well for us." As for Bill, she said, "I think he'll be happy to let me answer it."

10:55 a.m.
WikiLeaks chief Julian Assange says he wasn't trying to influence the U.S. presidential election when his organization published hacked emails from Hillary Clinton's campaign.
In a statement Tuesday, Assange denied he was trying to support Green Party candidate Jill Stein or take revenge for the jailing of former U.S. intelligence analyst Chelsea Manning.
Manning was sentenced to 35 years in prison for leaking secret U.S. government documents to WikiLeaks.
Assange suggests WikiLeaks would publish material on Clinton's Republican rival Donald Trump, if it received appropriate material and judged it newsworthy.
Assange said Wikileaks has not yet received information on the campaigns of Trump, Stein or other candidates "that fulfills our stated editorial criteria."

9:55 a.m.
As voters cast their ballots for president, some are convinced, while others are holding their breath.
In Indianapolis, 50-year old homemaker Ranita Wires said she voted for Hillary Clinton because she trusts her, but said "this has been the worst," and she's "so glad it's over."
Craig Bernheimer voted for Donald Trump at his local polling station in Tulsa, Oklahoma early Tuesday, saying it has more to do with "what the other didn't bring."
New Mexico truck driver Richard Grasmick said he admired Libertarian candidate Gary Johnson and intended to vote for him, but grew disillusioned by Johnson's televised flubs on foreign affairs issues.
He said, "I wanted to go with Gary but he failed me." Grasmick voted for Donald Trump instead.

9:20 a.m.
Lines were long in some places, but few voters heading to the polls early Tuesday appeared to be encountering problems.
Presidential elections usually include sporadic voting problems, such as machines not working properly. Calls to Election Protection, a national voter helpline, included people reporting long lines as a result of machine problems in three precincts in Virginia. And election officials at a handful of precincts in Durham County, North Carolina, were using paper roll books after technical issues with computer check-in.
Ahead of the election, there was anxiety over whether voters would face problems. Republican presidential candidate Donald Trump said the election was rigged and Democrats warned that Republicans were planning to intimidate voters. There were also concerns about hackers disrupting election systems.

Donald Trump's eldest son says that his family will "respect the outcome" of a "fair election."
Donald Trump, Jr. told CNN's New Day Tuesday that he thinks his father "will remain involved somewhat" if he loses the election. He said he hopes that the energy surrounding his father's campaign "goes back to the people we are trying to fight for, the people who haven't had a voice in a long time."
He said, in retrospect, that "hopefully we shed some light on the process," and enabled people to speak their minds freely, "without being put in some basket, without being boxed in a corner."

Women across the United States are wearing pantsuits Tuesday in a show of support for Hillary Clinton.
Many were inspired by a Facebook group called Pantsuit Nation that has more than 2 million members. Some are also wearing white in honor of the suffragists who wore white when they fought for women's voting rights in the early 1900s.
In Alexandria, Virginia, Heather O'Beirne Kelly says she's wearing a white pantsuit, inspired by the Facebook group and organized efforts to get women to wear white to vote.
New Yorker Denise Shull tried to buy a white pantsuit on Amazon, but they were sold out. She's wearing a black-and-white suit to support Clinton, but also to symbolize "women making progress."

President Barack Obama is keeping up an Election Day tradition: a game of pick-up basketball with friends.
Obama arrived at the gymnasium at the Army's Fort McNair in the District of Columbia around 8 a.m. He wore dark, casual clothes and a baseball cap, and carried a pair of high-top athletic shoes. The White House didn't say who the president would be playing with.
On the day of his re-election in 2012, Obama's basketball teammates included former Chicago Bulls player Scottie Pippen.
Obama started the Election Day tradition during the 2008 presidential campaign.

Eric Trump said, "we've seen states where a few thousand votes can make a difference."

Trump said he's spent over $100 million of his own money on his campaign. Federal Election Commission reports, however, show he's more than $30 million short of that claim. According to fundraising records, Trump's investment so far is about $66 million

The GOP nominee tells his final rally crowd in Grand Rapids, Michigan that: "If we don't win, this will be the single greatest waste of time, energy and money in my life."
Trump's final event at a local convention center was surprisingly staid, with none of the theatrics of an earlier rally in a packed arena in New Hampshire.
As he spoke, dozens of people streamed toward the exit, forming a procession in front of an area where reporters were stationed.
Some said they were trying to get closer to the door. But most said they were leaving because they were tired, wanted to beat traffic or had heard enough.
