Donald Trump’s second inauguration was unusual for many reasons, but the focus from both his supporters and critics on the actions on his very first day in office was particularly unique and possibly a new tradition for presidents to come.

Michelle Obama skipped the ceremony but former Presidents Joe Biden, Barack Obama, George W. Bush, and Bill Clinton attended Trump's inauguration.

Bill and Hillary Clinton have arrived at Donald Trump’s inauguration. The prominent Democratic couple showed a united front as they walked into the U.S. Capitol in Washington, D.C., for the ceremony.

As President Joe Biden prepared to pass the baton to President-elect Donald Trump, he followed the tradition of leaving his successor a note.

Donald Trump will be sworn in for a second term as president Monday—with every living former president, billionaires like Elon Musk and Mark Zuckerberg, Carrie Underwood, the Village People and several foreign leaders getting invitations.

Rather than wear MAGA red or bipartisan white, they dressed in the color of democracy. Bill, the 42nd U.S. president, was sharp in a dark navy suit, white shirt, and bright blue tie. Hillary coordinated in her own power suit, composed of a buttoned-up coat and tailored pants, in a deep royal blue. Her coat was adorned with a gold-and-blue pin.

Many were quick to notice Michelle Obama's absence on Inauguration Day, but the former first lady had a message to share on social media as questions over why didn't attend swirl.

Bill and Hillary Clinton were less than impressed by Donald Trump’s inaugural speech, a fact which they made clear with subtle snark. The address that followed Trump’s swearing-in on Monday was tinged with vindication.

Inauguration Day festivities brought plenty of high-profile style on everyone from incoming political figures to inauguration performers. "Good Morning America" is taking a closer look at the standout looks of the day from Ivanka Trump's sleek, deep green ensemble to Usha Vance's soft pink coat with a matching scarf.

A pastor, his eyes closed, preaches his heart out for history. A former president spots an acquaintance, then grins and winks.
