"It is my greatest honor and privilege to have been your president," he said to cheers. "I wish the new administration great luck and great success, and I think they'll have great success. They have the foundation to do something really spectacular."
The tone was a shift from previous weeks, in which continued to insist without evidence that he did not lose the election, an insistence that culminated in a mob of his supporters attacking the Capitol in an effort to stop President-elect Joe Biden's election from becoming official.
Breaking with decades of tradition, Trump will not participate in the peaceful transition of power and is skipping the inauguration. He opted for a rally-like setup at the military airfield, complete with large speakers blasting his campaign playlist, American flags, and several hundred gathered supporters.
He did not mention Biden by name in his remarks, instead urging supporters to credit him for future economic and coronavirus victories.
Trump's brief speech diverged from the prepared words aides had distributed ahead of the send-off. His remarks were off-the-cuff, and somewhat somber in tone. Trump touted a few items of his presidential legacy, including Space Force and judicial confirmation, and said his team had "left it all, as they say, on the field."
He thanked his family, Chief of Staff Mark Meadows, First Lady Melania Trump, and Vice President Mike Pence, and hinted at his own political future.
"We will be back in some form," he said.
The outgoing president typically departs shortly after the incoming president is sworn in, on a special air mission government jet. But Trump, who fought bitterly to overturn the results of the 2020 election, opted to orchestrate an alternative fanfare-filled exit while he is still commander-in-chief and can fly on Air Force One en route to his Mar-a-Lago home in Palm Beach, Florida.
There were a number of notable absences at the send-off: Pence did not attend, along with several former senior aides who were invited. A White House official and source familiar with the matter told NBC News on Tuesday that it was not logistically feasible for Pence to attend the sendoff as well as the inauguration.
The president’s final days were unusually quiet. Banned from posting on social media accounts, the president’s frequent missives — that often upended the business of government — were absent. Trump’s last public event before today’s departure from the White House was a week ago, when he went to the border to tout his border wall construction.
Pence has assumed many of the duties traditional reserved for the outgoing commander-in-chief, like thanking troops at Fort Drum over the weekend. He will continue that ceremonial role during Wednesday’s inauguration.
Meanwhile at the White House, staffers and movers are finalizing the transition of the residence and West Wing, packing up and disinfecting, because of the COVID-19 pandemic, ahead of the Biden administration's arrival shortly after noon.
