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

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.

The men who held the nation’s highest office before President Trump have all remained mum on his taking the presidency on Monday.

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.

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.

Donald Trump’s second inauguration as the 47th President of the United States took place on Monday in Washington, D.C. Following tradition, the day began with a worship service at St. John’s Episcopal Church and a White House meeting between incoming and outgoing presidents.

Clinton was caught on camera snickering as Trump vowed to change "the name of the Gulf of Mexico to the Gulf of America."

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.
