Campaign rival Hillary Clinton was present for the ceremony, sitting just a few seats away from Trump. She tweeted to her fans and followers, reassuring them she "will never stop believing in our country & its future."

Trump fans were at the nation's capital for the inaugural celebrations, many wearing red hats with his popular campaign slogan "Make America Great Again."

"I'm here for history," said Kevin Puchalski, a 24-year-old construction worker who drove from Philadelphia to attend the swearing-in. "This is the first president that I voted for that won." His big hope: Trump builds that promised wall on the U.S.-Mexican border. "Keep the illegals out," he said.

Meantime, dozens of Democratic lawmakers were boycotting the ceremony on Capitol Hill. Trump faces a divided nation that is still reeling from the long and controversial presidential race.

Immediately after his and Vice President Mike Pence's swearing-in, Trump embraced members of his family and waved to the crowd on the National Mall.

The president started his inauguration day with a morning tweet to his country saying, "It all begins today!" and "THE MOVEMENT CONTINUES - THE WORK BEGINS!"

Protesters came out early, some trying to block inaugural visitors from passing through security checkpoints, some wearing orange jumpsuits with black hoods over their faces.

Meantime at the White House, moving trucks were on standby for the new first family, while the former was set to head out.

Obama also took to Twitter on his last hours as president, thanking the public for making him a "a better leader and a better man."

He continued with follow-up tweets, making a promise to the people he "will be right there with you as a citizen."

After the inauguration ceremony, the Trumps escorted the Obamas to the presidential plane, but it won't be referred to as Air Force One because that designation only applies when the current president is on board.

Following plans to address a farewell gathering of staff at Joint Base Andrews, Obama and his family plan to travel to Palm Springs.

It's unclear how long the Obamas will be in Palm Springs, but they aren't expected to host any public events while in California.

The Obamas have rented a home in Washington and intend to live there as private citizens until Sasha finishes high school.
