Donald Trump will be sworn in for a historic second term as US president Monday, promising a new "golden age" for America as the world braces for a return of his unpredictable leadership.
Freezing weather has forced the 78-year-old's inauguration at the US Capitol indoors, but the first hours of the most extraordinary comeback in American politics will be a blaze of activity.
The Republican vowed to unleash a blitz of executive orders undoing Joe Biden's legacy upon his return to the White House, and to launch immediate deportations of undocumented migrants.
If Trump painted a dystopian picture of "American carnage" at his first inauguration in 2017, this time around he is offering a more upbeat promise of a "brand new day" for the United States. "I will act with historic speed and strength and fix every single crisis facing our country," Trump told a huge inauguration eve rally where he also danced with the Village People band.
