US President Joe Biden has begun to undo some of Donald Trump’s key policies, hours after being sworn in.
In his initial acts as the 46th US president, he signed 15 executive orders – the first to boost the federal response to the coronavirus crisis.
Other orders reversed the Trump administration’s stance on climate change and immigration.
President Biden set to work at the Oval Office having been sworn in earlier on Wednesday at the US Capitol.
The inauguration was unlike any other due to coronavirus restrictions, with few present to witness the oaths and ceremonies.
Donald Trump – who has still not formally conceded the presidency to Mr Biden – snubbed the event in a departure from longstanding precedent.
