Four years and 14 days after he told his supporters to march on the U.S. Capitol in a bid to subvert the election results and keep himself in power, Donald Trump will be sworn back into office Monday inside the very building those supporters violently attacked. He will be welcomed back into office by leaders of both parties on what is expected to be the coldest Inauguration Day since 1985. 

Roughly a quarter million people were expected to attend his speech, according to the Secret Service, on a day where forecasts say temperatures will barely break 20 degrees. But on Friday, Trump announced his swearing-in ceremony will be moved inside to the U.S. Capitol Rotunda and his remarks will be shown at Washington’s Capital One Arena. A rally at the arena was already planned for the eve on the inauguration Sunday and will go on as scheduled.

While Trump’s transition team has yet to preview his second inaugural address in great detail, the incoming president is not one for short speeches. His rally speeches often extend well beyond the one-hour mark and his acceptance speech at the Republican National Convention last summer was the longest in U.S. history. But his 2017 inaugural address, when he spoke of “American carnage” and “the forgotten men and women of our country” lasted roughly 15 minutes and was among the shorter speeches of the last 50 years. 

“We assembled here today are issuing a new decree to be heard in every city, in every foreign capital and in every hall of power,” Trump said then. “From this day forward, a new vision will govern our land. From this day forward, it's going to be only America first — America first. America will start winning again, winning like never before.”

Unlike his plot to stay in office in 2021, this time Trump will return to power legitimately and on the back of a decisive electoral victory over the Democratic Party and its standard-bearers — President Joe Biden and Vice President Kamala Harris — who argued in their campaigns that Trump is a fascist who would do great harm to the nation. 

Having failed at their stated mission, Harris and Biden will instead welcome Trump back to Washington and attend his second inauguration in the name of ensuring “a peaceful and orderly transition of power to ensure we lead by the power of our example,” as Biden put it in his Oval Office farewell address last week. Their attendance — and the expected attendance of every living president and their spouses, sans Michelle Obama — is a courtesy Trump did not offer in kind in 2021. He left Washington without attending Biden and Harris’ inauguration after his monthslong campaign of lies, disinformation and intimidation to overturn his 2020 election loss failed.

But despite his failure then and calls from within the Republican Party to move past the Trump era, the 78-year-old spent the ensuing four years solidifying his place at the center of his party and now returns to Washington stronger than ever and with promises to deport millions of people, impose stiff tariffs on foreign goods and wield the full strength of the federal government against his political enemies.

He will begin his first day in office alongside a loyal Republican majority in Congress that he is already reshaping, a 6-3 conservative Supreme Court that includes three of his nominees and an increasingly deferential billionaire class that has poured millions into his campaign and inaugural committee.

None has been more integral to his return to power than far-right billionaire and Tesla CEO Elon Musk, who personally campaigned for Trump and is set to play a significant role in shaping his second administration from the outside. But many of the most influential and wealthy American business leaders are planning to make the trek to Washington for Trump’s reascension. A source familiar with the inaugural plans confirmed to Spectrum News that business leaders expected to attend included Meta CEO Mark Zuckerberg, Amazon founder Jeff Bezos, Apple CEO Tim Cook and TikTok CEO Shou Zi Chew, who is currently fighting for the future of his company in the United States. 

Google, Meta, Amazon, Cook personally and OpenAI CEO Sam Altman all each donated $1 million to Trump’s inauguration fund, which has raised a record $170 million for the main event and other associated festivities. Boeing, Chevron, Ford, General Motors, Toyota, Uber and Pfizer are among the other major corporations to similarly fund Trump’s second inauguration. Last week, Coca-Cola Company CEO James Quincey hand delivered “the first ever Presidential Commemorative Inaugural Diet Coke bottle” to Trump, a longtime lover of the beverage, in Florida.

“One of the things that I'm optimistic about with President Trump is I think he just wants America to win,” Zuckerberg said on Joe Rogan’s podcast earlier this month shortly after overhauling his company’s policies on speech, fact-checking and political content to more closely align with Trump’s vision of the world.

Zuckerberg is co-hosting one of the many inaugural balls in the Washington area Monday, alongside GOP megadonor Miriam Adleson, casino magnate and U.S. ambassador to Italy nominee Tilman Fertitta, and Chicago Cubs co-owner Todd Ricketts, the brother of Nebraska Sen. Pete Ricketts. 

Other notable inauguration attendees include far-right world leaders, including Italian Prime Minister Giorgia Meloni and Argentinian President Javier Milei. Trump also extended the invite to China leader Xi Jinping and Hungary’s authoritarian Prime Minister Viktor Orbán. Neither man is expected to make the trek, though Xi will send an emissary in his place: Vice President Han Zheng, who holds a largely symbolic position in the Chinese government. 

Trump will take office with a slew of day-one promise to fulfill, including mass deportations on a scale the United States has never seen. In the weeks since his reelection, he has also repeatedly proposed U.S. expansion into Canada, Greenland and Panama, declining to rule out the use of military force in the latter two. And the more than 1,600 people charged in connection to their role in the Jan. 6, 2021, attack on the U.S. Capitol are awaiting news on their pardons Trump has promised.
