Biden calls for unity, promises peaceful transition

US President Joe Biden has given his first speech since voters went to the polls this week to choose his successor. He's called for unity and promised a peaceful transition of power to President-elect Donald Trump. Biden spoke from the White House on Thursday. He stressed he accepts the voters' choice, and underscored his faith in the US electoral system.

Biden also encouraged his staff to work until the end of his term. US media say Trump's transition team has started working. And their reports have focused on who could fill important posts in the new administration. Possible figures include US billionaire Elon Musk. He supported Trump during the campaign and was reportedly at Trump's home on Wednesday.
