The race for the US presidency is nearly over!
In his acceptance speech, he pledged to unify the country and declared it a “time to heal”. Donald Trump responded by calling the election fraudulent but has so far provided no evidence to support this claim.
Mr Biden and his running mate, Kamala Harris - who is the first female, the first black person and the first Asian-American to be vice-president - will be sworn in on January 20th 2021.
Why has Donald Trump's reaction caused outrage?
Donald Trump has made several false claims about election fraud without offering any firm evidence. It has angered and shocked people across both parties in America as it looks like he's discrediting the election process. America prides itself on holding fair and clear elections, and a peaceful transfer of power when a new president is chosen. Watch what Donald Trump said on Thursday below.

What happened earlier in the election race?
On Monday October 26th, Amy Coney Barrett was sworn in as the latest Supreme Court judge to be chosen by President Trump. Donald Trump had vowed to fill the empty seat on the United States Supreme Court after the death of the pioneering judge Ruth Bader Ginsburg (read more about her here!). He nominated Amy Coney Barrett. The Supreme Court is made up of 9 judges and is the highest in the land - it settles really big disagreements, including to do with the law. It is made up of judges nominated by Democratic presidents and Republican presidents. Most recently, it has had 5 judges nominated by Republican presidents, and 4 from the Democrats. Ruth Bader Ginsburg was nominated by Democratic president Bill Clinton.

On Monday 28th September, we woke up to hear that The New York Times have seen details of how much tax Donald Trump has paid over the past 15 years. Is it good news for the president? Probably not - it shows he paid very little tax - by trying to avoid tax and also because his businesses were losing more money than they made. It doesn't reflect well on a president who has always talked of his business success as a reason why he is good for America. Find out more on this story here.
On the same day, Channel 4 published a report on the Trump campaign deliberately trying to deter (put off) black voters from voting in 2016. Read the full report here!
President Trump and Joe Biden have disagreed over the decision not to charge any police officers over the killing of Breonna Taylor, an unarmed black woman who was shot six times in a police raid on her home in March. Read what happened to her here.
Breonna's family sued the Kentucky city for the death and a £9.4m settlement was agreed. However, they also pressed for charges for the officers who fired the shots, but this did not happen.
About the decision, Donald Trump said he "thought it was really brilliant".
However, Joe Biden, said the decision "does not answer" the call for justice, while telling protesters to act peacefully.
The killing of Breonna Taylor, and the decisions made afterwards, are stirring a lot of debate about police treatment of black people in the United States, ahead of the US election. Read more about the reaction here.
