WASHINGTON — President-elect Donald Trump's inauguration ceremony is moving indoors to the Capitol rotunda because of a frigid weather forecast in the nation's capital Monday, the president-elect announced on social media Friday.

The sudden weather-induced change forced a scramble for hundreds of thousands of people who had spent months planning for the swearing-in of the nation’s 47th president.

The potential change, a rare break with tradition, would deny Mr. Trump the pomp and large audience he hoped for at his second swearing-in.

President-elect Donald Trump announced Friday that he will move the inauguration ceremony indoors as Washington, DC prepares for record low temperatures. The ceremony will now take place inside the Capitol rotunda.

Bad weather forecasts mean President-elect Donald Trump will take the oath of office from inside the Capitol Rotunda and people visiting Washington from around the country won’t be able to see it in person.

The pageantry and parties surrounding President-elect Donald Trump’s inauguration kick off this weekend with fireworks and a rally before Monday’s Inauguration Day ceremony, parade and balls.

The relationship between President-elect Trump and his former vice president, Mike Pence, was irreparably broken when Mr. Pence refused Mr. Trump’s efforts to overturn the election.

The list of big-time events that will take place on Trump’s watch is formidable: There is the 250th anniversary of the Declaration of Independence — the U.S. Semiquincentennial celebration of the nation’s birthday next year. The 2026 World Cup. The 2028 Olympics. (And, on a more somber note, the 25th anniversary of the Sept. 11 attacks.)

As Donald Trump's inauguration approaches, families are rushing to resolve their cases before the start of his second term, amid uncertainty about the future of DACA protections. This follows the president-elect's previous attempts to end DACA during his first term and his comments labeling the program as illegal.

The Rotunda is prepared as an alternative for each inauguration in the event of inclement weather. The swearing-in was last moved indoors in 1985, when President Ronald Reagan began his second term. Monday’s forecast calls for the lowest Inauguration Day temperatures since that day.

As President-elect Donald Trump prepares to return to the Oval Office on Monday, several groups are working to ensure that Monday's inauguration is safe.
