Donald Trump is sworn in as the 47th president of the United States.
Trump was sworn in on Monday at the Capitol Rotunda by Chief Justice John Roberts.
At the ceremony, Trump vowed to make America "greater, stronger and more exceptional" than ever before.
Former Presidents Bill Clinton, George W. Bush and Barack Obama attended the inauguration. Tech tycoon and Trump's biggest supporter Elon Musk also attended the ceremony.
The inauguration ceremony took place indoors due to the cold temperatures in Washington, DC, unprecedented in decades.
In the meantime, Trump is expected to sign a barrage of executive orders following the ceremony.
According to an incoming White House official, the new orders include tougher anti-immigration measures as well as pardons for people convicted for their role in the Capitol Hill attack on January 6, 2021.
Ahead of his inauguration, Trump met at the White House with the outgoing president Joe Biden – a courtesy the Republican had denied his Democratic successor in 2021.
Earlier, Trump had attended a church service. Alongside, Meta's Mark Zuckerberg, Amazon's Jeff Bezos, Google's Sundar Pichai and Apple's Tim Cook, some of the most powerful tech moguls in the world, attended the service.
