Trump's second inauguration has had notable support from numerous tech giants.
President-elect Donald Trump laid a wreath at Arlington National Cemetery and then held a "Make America Great Again Victory Rally" in Washington on Sunday ahead of Monday's swearing-in ceremony.
Trump's inauguration has been moved indoors because of frigid temperatures expected in the nation's capital on Monday. Trump said he'll be sworn in and deliver his inauguration address inside the Capitol Rotunda.
Trump and his family arrived at his golf course – Trump National Golf Club in Sterling, Virginia – for a closed reception with a who's who of allies.
Guests include cabinet nominees such as Pete Hegseth, Kristi Noem and Lee Zeldin.
Trump and his family will then view fireworks at 9 p.m. from a viewing balcony.
