Joe Biden is projected to win the election and become the 46th President of the United States.
After a nail-biting race, the Democratic candidate gained an unbeatable lead in Pennsylvania, taking its 20 Electoral College votes and past the 270 needed to win the White House.
Kamala Harris will now become the first female US Vice-President in history.
Mr Biden said: "America, I’m honored that you have chosen me to lead our great country.
"The work ahead of us will be hard, but I promise you this: I will be a President for all Americans — whether you voted for me or not.
"I will keep the faith that you have placed in me."
The outcome makes Donald Trump the first one-term president since 1992, when George HW Bush failed to clinch four more years.
