When addressing Americans, the president-elect vowed to “restore the soul of America” through his presidency.
“I sought this office to restore the soul of America. To rebuild the backbone of the nation — the middle class,” he said.
Then he made a clever nod to Mr Trump’s “Make America Great Again” slogan.
“To make America respected around the world again and to unite us here at home,” Mr Biden said, adding: “It is the honor of my lifetime that so many millions of Americans have voted for this vision. And now the work of making this vision real is the task of our time.”
Mr Biden’s victory speech comes after four days of the American public waiting for a winner to be determined in the 2020 election. On Saturday morning, the Associated Press and other news organisations called the battleground state of Pennsylvania as Mr Biden’s, putting him over the necessary 270 electoral votes he needed to take the White House.
Although Mr Trump has yet to concede, Mr Biden also reached out to Trump supporters in his speech in an effort to unite the country.
“For those of you who voted for President Trump, I understand the disappointment tonight. I’ve lost a couple of times myself. But now, let’s give each other a chance,” Mr Biden said.
“Let’s give each other a chance and stop treating each other like enemies. We are not enemies. We are Americans. This is the time to heal,” he added.
Whether the sitting president will concede remains unknown. Mr Trump has claimed voter fraud has impacted the election results, a claim he’s backed up with no evidence.
“I WON THIS ELECTION, BY A LOT,” he tweeted right before the race was called for Mr Biden.
