Masks are now mandatory and the United States has rejoined the Paris Climate Accords, as Joe Biden steps into his first term as President of the United States of America.
The 46th President wasted no time in signing several executive orders reversing Donald Trump's policies, just hours after being sworn in at Capitol Hill in a ceremony vastly different to ever before.
Amid claims of rigged elections, deadly riots and impeachments, Joe Biden was sworn in at highly-secured ceremony in Washington DC on Thursday morning AEDT.
The historic ceremony has security tightened and traditions tweaked to ensure the safety of the incoming leaders.
For example, Biden will not take part in the usual parade down Pennsylvania Avenue, instead getting a military escort to his new home - the White House.
