Last month Mr Trump became the first president in US history to be charged with misconduct – or impeached – twice by the lower chamber of Congress.
Republicans and Democrats in the House of Representatives voted to pass an article of impeachment that accused Mr Trump of “incitement of insurrection”.
The article alleged that Mr Trump made false allegations of election fraud and encouraged his supporters to storm Congress on 6 January.
Now a trial is being held in the upper chamber of Congress, the Senate, which will decide whether to convict or clear Mr Trump of the charge.
This is an unprecedented moment for the US, which has never put an impeached president on trial after they have left office.
