It's been a whirlwind first 24 hours in the Oval Office for president Joe Biden, who yesterday signed the first orders to rid the country of some of Donald Trump's policies.
He's re-joined the Paris Climate Accords and World Health Organisation, revoked the so-called Muslim travel ban, and funding for the border wall has been cut off.
Biden's also cleansing the office itself, vowing to fire anyone who treats their co-workers with disrespect.
