Highlights from President-elect Donald Trump's 1st Inauguration Day; what to expect from Monday

Celebrities and top business leaders are rallying around the incoming 47th president of the United States - a stark contrast to the inaugural ceremonies in 2017. 

Trump, in November, won the 2024 presidential election in a landslide. He dominated both the Electoral College and the popular vote to defeat Vice President Kamala Harris after a historic campaign cycle. 

Since his massive victory, the president-elect has seen support from his traditional allies - including Republicans in Congress and GOP governors across the nation - as he builds out his incoming administration. 

However, he has also been embraced by top executives in the business world and Silicon Valley - individuals who had not been particularly cozy with Trump or his allies during and after his first administration. 

Leading up to the inauguration, Bezos, Zuckerberg, Apple CEO Tim Cook and executives from Google, Microsoft, Boeing, Ford Motor Co. and more, committed at least $1 million each to Trump's inaugural fund - a total about-face from the first Trump inauguration. 

Trump will also have union leaders at his inauguration, representing the broad coalition of support he has seen since his victory, including International Brotherhood of Teamsters President Sean O'Brien and members of the Firefighter's Union. 

Underwood's performance will come just before Trump takes the presidential oath of office for the second time. 

Joining Underwood during the swearing-in ceremony will be opera singer Christopher Macchio, who is expected to perform the national anthem. 

Reports suggest other top music acts will make their way to Washington, D.C., for performances, including Jason Aldean, Rascall Flatts, Kid Rock, Billy Ray Cyrus, Village People and more. 

Additionally, the 2017 inauguration weekend was also marred by protests across Washington, D.C. 

Protesters created chaos across the city ahead of Inauguration Day in 2017, shattering glass storefronts and torching cars, with police arresting more than 200 people in demonstrations that spanned several days.

Trump's actual swearing-in on Capitol Hill and the parade to the White House happened, however, without any incident.

However, the day after Trump was sworn into office as the 45th president of the United States, several hundred thousand people from across the country descended on the nation's capital to protest his presidency in the "Women's March on Washington."

Many of the protesters were indeed women and were largely peaceful compared to the rioters who wreaked havoc in Washington, D.C., days earlier. The march moved from the National Mall to the streets while the newly inaugurated president attended a National Prayer Service after waking up in the White House for the first time.

Celebrities like America Ferrera, Madonna, Ashley Judd, Cher, Katy Perry, Amy Schumer, Scarlett Johansson, Julianne Moore, Michael Moore, Debra Messing, Patricia Arquette and others attended the march.

Madonna, during that protest, said she had "thought an awful lot about blowing up the White House."

However, Trump's second inauguration is expected to be a celebration - the official Inauguration weekend will begin with a large fireworks display Saturday night. 

On Sunday, there will be a wreath laying ceremony at the Tomb of the Unknown Soldier at Arlington National Cemetery and a "Make America Great Again" rally, where Trump will deliver remarks, followed by a candlelit dinner. 

The president will then attend three official inaugural balls and is expected to deliver remarks at each. 

"President Trump is dedicated to uniting the country through the strength, security, and opportunity of his America First agenda," Trump Vance Inaugural Committee, Inc. Co-Chairs Steve Witkoff and Kelly Loeffler said. "The 2025 inaugural celebrations will reflect President-elect Trump's historic return to the White House and the American people's decisive vote to Make America Great Again."
