Donald Trump has arrived at his resort home in Mar-a-Lago, Florida, after leaving the White House for the last time.
As Joe Biden's inauguration ceremony was under way in Washington - an event Mr Trump snubbed - the former president flew to Palm Beach aboard Air Force One and then travelled in a motorcade to his home.
Hundreds of fans lined the road waving Trump campaign flags and US flags.
The motorcade slowed down to a crawl, apparently so that Mr Trump could engage with them.
One woman holding a homemade "Trump landslide" sign was in tears.
There was also a smattering of pro-Biden signs. One aimed at Mr Trump said: "You're fired, you loser."
At a farewell ceremony earlier at Joint Base Andrews outside Washington, he said it had been an "incredible four years" and promising to be "back in some form".
"We've accomplished so much together," he said. "I will always fight for you."
Speaking earlier at the White House, Mr Trump said: "I just want to say goodbye," calling his time in office "the honour of a lifetime".

President Trump broke days of silence yesterday with a pre-recorded farewell video address in which - for the first time - he asked Americans to "pray" for the success of the incoming administration.
But the 74-year-old has yet to personally congratulate Mr Biden on his win, and the 11th-hour message followed months spent persuading his Republican followers that Democrat cheated his way to election victory.

Mr Trump has hinted at running for president again in 2024, but faces a trial in the Senate over his role in the 6 January storming of the US Capitol by his supporters and a potential ban on holding office in the future.
