Washington (CNN)President Joe Biden’s inauguration on Wednesday looked a bit different from past ceremonies ushering in a new administration.
The day’s historic events navigated heightened security measures in Washington, DC, Covid-19 precautions and the absence of the outgoing President, the first time that’s happened in more than a century and a half.
Still, the unprecedented day closed with fireworks and messages of unity and hope.
Here are the highlights from the inauguration of America’s 46th president:
Trump leaves the White House
Though former President Donald Trump did not attend Biden’s swearing-in ceremony, he was publicly seen several times, including when he left the White House as president for the last time shortly after 8 a.m. ET.
Before boarding Marine One with the former first lady, Trump told reporters at the White House it was a “great honor” to serve as 45th President of the United States before saying goodbye.

Trump also held a final farewell ceremony, where both he and former first lady Melania Trump delivered remarks.
The former President thanked his family and chief of staff, and promised to “always fight.” He also wished the incoming Biden administration “great luck,” though he didn’t mention his successor by name.
Melania Trump, meanwhile, told attendees that “being your first lady was my greatest honor.” The two then boarded Air Force One for the last time just before 9 a.m., taking the presidential plane to their Florida home.
Biden attends church
Just after the Trumps boarded Air Force One, Biden and first lady Jill Biden headed over to Cathedral of St. Matthew the Apostle in DC, where they attended mass with their family, Vice President Kamala Harris and her family. They were joined by the congressional leaders of both parties.
Incoming presidents typically attend services on the morning of their inauguration, often at St. John’s Episcopal Church, a small church across Lafayette Square from the White House known as “The Church of the Presidents.”
Biden arrives at Capitol
Biden arrived at the US Capitol shortly after 11 a.m. and Harris and her husband, Doug Emhoff, accompanied him and Jill Biden up the steps of the iconic building.
When Biden arrived at the inauguration stage, he greeted his predecessor and former boss, former President Barack Obama, on his way to his seat. He received a lengthy ovation from those gathered on the stage and sat down at 11:19 a.m.
Harris and Obama first bump
As she walked to her seat on the inaugural stage, Harris shared double fist bumps with Obama.
The gesture, exchanged shortly before Harris was sworn in as vice president, carried symbolic weight as Obama and Harris made history as the first African Americans to serve as president and vice president, respectively.
Harris similarly fist bumped Michelle Obama, who made history as the country’s first African American first lady.

Biden completed his oath of office at 11:48 a.m., using a treasured family Bible that dates to the 19th century and was held by Jill Biden. The oath was administered by Chief Justice John Roberts.
After being sworn in, Biden delivered an inaugural address in which he called for unity and pledged to be a “president for all Americans,” including those who did not support his campaign at his inauguration address.
The President also offered a forewarning his remarks, describing the nation as weathering a “winter of peril” amid the coronavirus pandemic.
Singers and poet perform
The inauguration also featured several celebrity performances, including a rendition of the National Anthem by Lady Gaga. Jennifer Lopez sang a medley of American musical selections including “This Land is your Land” and “America the Beautiful,” and Garth Brooks performed “Amazing Grace.”
Amanda Gorman, the nation’s first-ever youth poet laureate, also delivered a poem in which she challenged Americans to “leave behind a country better than the one we were left” and unify.
Pence and Harris share a laugh
Former Vice President Mike Pence, who attended the ceremony even though Trump did not, was met with bipartisan applause when he and his wife, Karen Pence, walked out onto the inaugural stands earlier Wednesday.
Later, as Harris and Emhoff bid the Pences farewell outside the Capitol, the two couples shared a laugh as the Pences began their private life.

Biden signed three documents after the ceremony outside the Capitol finished, including an Inauguration Day Proclamation, nominations to Cabinet positions and nominations to sub-Cabinet positions.

Harris swears in new Democratic senators
Harris returned to the Capitol to swear in three new Democratic senators: Georgia’s Jon Ossoff and Raphael Warnock, and California’s Alex Padilla, who replaced Harris in the chamber.
Their swearing-in officially gave Democrats control of the Senate for the first time since they lost the chamber in 2014. Harris will wield power as the Senate’s crucial tie-breaking vote.
Harris laughed as she read a line referencing her own resignation from the Senate as part of the swearing-in.
“The chair lays before the Senate two certificates of election and a certificate of appointment to fill the vacancy created by the resignation of former Sen. Kamala D. Harris of California,” Harris said.
“Yeah, that was very weird.”
Biden takes aim at Trump’s legacy with early executive actions
Biden got down to work in the White House later Wednesday, finalizing over a dozen executive moves by signing a flurry of executive orders, memorandums and directives to agencies.

Making explicit that he wanted to break with the toxic environment that pervaded the West Wing during the previous administration, Biden said he wanted his staff governed by collegiality and respect.
“If you’re ever working with me and I hear you treating another colleague with disrespect, talking down to someone, I will fire you on the spot,” he said.

White House press secretary Jen Psaki began her tenure by holding the administration’s first press briefing Wednesday night and vowing to return to fact-based briefings.
Psaki said that upon accepting the job, she was committed to “bringing truth and transparency back to the briefing room.”
She continued, “There will be times when we see things differently in this room, I mean among all of us. That’s OK. That’s part of our democracy, and rebuilding trust with the American people will be central to our focus in the press office and in the White House.”

The star-studded 90-minute program kicked off with Bruce Springsteen performing his song “Land of Hope and Dreams.”
