Donald Trump’s inauguration moved indoors due to the “dangerous” cold.

President-elect Donald Trump has confirmed that his Jan. 20 inauguration speech will be delivered indoors due to dangerously cold weather expected next week in Washington.

The speech, along with others, will now be delivered inside the rotunda of the U.S. Capitol, rather than outside the building.

The inaugural show will also be held at the Capital One Washington Arena in downtown Washington, about 1 mile (1.6 km) away, along with the three inaugural balls.

The last president to be sworn in indoors was Ronald Reagan in 1985, when cold weather also hit the U.S. Capitol.

In a statement posted on the social media platform Truth Social, Trump said he “does not want to see people hurt or injured in any way” amid the freezing temperatures.

“These are dangerous conditions for tens of thousands of law enforcement, first responders, police K9s and even horses” as well as “hundreds of thousands” of supporters.

“Anyway, if you decide to come, dress warmly,” he added.

Capital One Arena will also be open for a live showing of the opening address.

Trump – who is scheduled to rally there on Sunday – said he would visit the square after being sworn in at the Capitol.

The planned presentation will now be conducted in a modified form. It is unclear whether it will now take place indoors.

Extreme cold was forecast for Washington, D.C., on Inauguration Day, with temperatures expected to reach as low as -11°C (12°F) and as high as -5°C (23°F). Taking into account the wind chill, the temperature will feel cooler.

The weather is part of a larger polar vortex that will cause temperatures to plummet across the United States.

“Everyone will be safe, everyone will be happy, and together we will make America great again,” Trump wrote.

Before the opening, organizers said that about 220,000 tickets will be distributed to watch the event on the grounds of the US Capitol.

Those without tickets will also be able to watch the festivities on the National Mall.

Alternative plans will now be needed for these visitors, as well as the tens of thousands more expected to arrive in the city.

Trump said other inaugural events, including his rally on Sunday and three separate state inaugurations on Monday evening, will go ahead as planned.

The move at home means a severely limited ability to swear in Trump on Monday, who is known to closely track attendance numbers at his public events.

After his first inauguration, he claimed that “a million and a half people” were in attendance on the National Mall.

But crowd size experts said the numbers were about a third of the estimated 800,000 to 1 million people who attended Barack Obama’s concert in 2009.

Only about 1,000 people attended Joe Biden’s inauguration at the Capitol due to coronavirus restrictions.

In 1841, then-President William Henry Harrison, 68, delivered the longest inaugural address in U.S. history in cold, wet conditions.

He came down with a cold and then pneumonia, and died exactly one month later, making his presidency the shortest in US history.
