Here are some of the striking moments captured by our photographers as U.S. voters went to the polls and the stories behind the images:
DONALD TRUMP by Tom Brenner
I live down the street from Donald Trump's campaign headquarters but had never noticed who worked there. When we were unexpectedly allowed onto the office floor, I was struck by the crowd of smartly dressed young people behind the president's re-election campaign - tense, tired and excited. It was around noon, but the clock on the wall had been stopped after counting down to midnight.
COOL CAT by Bryan Woolston
Just after noon on Election Day, I noticed a cat sitting on the shoulder of a voter at a polling station in Louisville, Kentucky. As I approached it turned to look at me. The man continued getting ready to cast his ballot as if having a cat on his shoulder while voting was completely normal - a bit of light relief on a stress-filled day.
