Watch: Trump promises 'brand new day' at pre-inauguration rally
Ahead of his return to 1600 Pennsylvania Avenue, President-elect Donald Trump addressed a raucous crowd of thousands in a Washington DC arena for a "Victory Rally" in which he offered a preview of the next four years.
The Republican promised to act unilaterally on a wide array of issues, using his presidential powers to launch mass deportation operations, slash environmental regulations and end diversity programmes.
He is expected to sign more than 200 executive actions today. This would include executive orders, which are legally-binding, and other presidential directives like proclamations, which are usually not.
"Every radical and foolish executive order of the Biden administration will be repealed within hours of when I take the oath of office," the incoming president said.
Trump promised executive orders that would ramp up artificial intelligence programmes, form the Department of Government Efficiency (Doge), make records available related to the assassination of John F Kennedy in 1963, direct the military to create an Iron Dome missile defence shield and eliminate diversity, equity and inclusion (DEI) policies from the military.

Good morning from the London newsroom where we're beginning our live coverage of Donald Trump's inauguration as 47th president of the United States.
The inauguration – the formal ceremony that marks the end of one president's time in office and the start of the successor's administration – is the most high-profile part of the transition of power between government leaders in Washington DC.
Today's events will include a formal swearing-in ceremony, as well as musical performances and a number of formal balls.
But freezing temperatures this year will move events indoors, with Trump and Vice-President-elect JD Vance set to take the oath of office in the United States Capitol Rotunda building.
On the eve of his return to the White House, Trump promised to sign a blitz of executive orders on his first day as president, telling supporters that he would move with "historic speed and strength" in the hours after taking the oath of office.
He is expected to sign more than 200 executive actions on Monday – we'll bring you more on that shortly.
We've got correspondents in Washington DC and across the US poised to bring you the latest details and analysis of this historic day and you'll be able to follow the build-up live right here, so stay with us.
