People arriving at some US polling stations have had to join the back of a long line, with many waiting hours to cast their vote in the presidential election.
At one location in Brooklyn, New York, the queue snaked around the block, turned another corner and continued down the street.
Joel Frenzer, 40, filmed the line of people waiting to enter his local polling station in the Prospect Lefferts Gardens area of the city not long after it had opened at 6am.
“I got to the end of that line, and I decided not to wait in line and went home instead,” Mr Frenzer told The Independent.
“I’m back right now and it’s somewhat shorter, but not much. I’m guessing I'll be here for 45 minutes.”
Similar scenes took place across the country, with voters waiting up to 90 minutes at one polling station in Detroit, reported the Washington Post.
And in North Hollywood in California, some people brought beach chairs to a polling station before dawn.
"I waited two hours in line to vote. So what? Others fought, bled and died for the right to vote. I owe them," wrote Harold Itzkowitz on Twitter.
While New York is not a swing state, Mr Frenzer said he and the people around him were "really excited by the turnout" and hoped his video could be a show of solidarity towards people in other states.
“I don’t think there are any problems, it’s just the number of people,” he said. “I’m voting for Hillary Clinton. It can’t be Trump.”
Another video of even more voters, some with young children, waiting outside the same polling station was also widely shared on Twitter this morning.
Long lines were also experienced in some areas during the 2012 election.
Harvard PhD student Stephen Pettigrew, who studies polling lines, told the New York Times while long queues did "give some indication of the health of our democracy," they could also suggest problems in some areas.
Mr Pettigrew has found lines are around twice as long in areas with mostly minority communities compared to in predominantly white areas.
He told the newspaper this could be because election officials may have reacted slowly to changes in voting demographics.
In 2012, the turnout of black voters was higher than that of white voters for the first time in history, according to CNN.
