Daily US Times: After departing the White House for the final time as president Donald Trump has vowed he will be “back in some form”.
Mr Trump told supporters as he prepared to fly to Florida that it had been “a great honour to be your president”.
Donald Trump is the first president to snub his successor’s inauguration since 1869 but did say: “I wish the new administration great luck and great success.”
Joe Biden took the oath of office by noon (17:00 GMT) in Washington amid heavy security.
Some 25,000 national guard troops guarded the inauguration ceremony following a deadly riot by violent pro-Trump supporters at the Capitol earlier this month.
Donald Trump delivered his final speech as president at Joint Base Andrews in Maryland, after flying there from the White House with First Lady Melania Trump.
In a typically unscripted speech, he highlighted his “amazing” achievements, citing the establishment of a “Space Force”, job creation, policies for veterans and on taxation, as well as the speedy development of Covid-19 vaccines.
He urged people to be “very, very careful” about the “horrible” coronavirus pandemic and paid respects to those who had suffered.
He added: “It’s been a great honour and privilege to be your president… I will always fight for you. I will be watching. I will be listening.
“I wish the new administration great luck and great success. I think they will have great success. They have the foundation to do something really spectacular.”
But, as with his farewell video address on Tuesday, he did not mention his successor Mr Biden by name.
