Mike Pence won't be part of Donald Trump's farewell ceremony to Washington, with the Vice President instead focusing on the inauguration of Joe Biden.
Mr Trump's departure is three hours before the inauguration, making it difficult for Mr Pence to attend both.
And Mr Pence has opted for the swearing-in of Mr Biden instead of the formal goodbye to his boss.
Mr Trump had been hoping for a large military ceremony to farewell him from the presidency.
But the Pentagon denied Mr Trump's request for a big event.

Instead he will board Air Force One at Joint Base Andrews and fly to his private country club Mar-a-Lago in Florida at 8am Wednesday local time.
The trip will be his last on Air Force One.
He will leave the White House via Marine One, the president's helicopter.
Mr Trump is the first president since Woodrow Wilson in 1921 to not attend his successor's inauguration. Mr Wilson at the time was seriously ill.

As a mob stormed the Capitol, some could be heard chanting "Hang Mike Pence". Mr Trump tweeted the vice president was a "coward" for not trying to overturn the election results.
Mr Pence was evacuated from the Senate a minute before the rioters entered the chamber.
Mr Pence and Mr Trump did not speak for days afterwards.
Former White House Communications Director Anthony Scaramucci has suggested his own invitation is indicative of a dwindling list of attendees.
"Trust me, that had to be a mass email if one of them got sent to me," he said.
"I am having my fingernails pulled out at that time, sorry I can't make it."

Mr Scaramucci famously lasted 11 days in the White House before he was fired, with his surname becoming a unit of measuring time in Washington.
"There is 1/11th of a Scaramucci left for Trump," Mr Scaramucci tweeted this morning.
Ex-senior White House staffers Don McGahn and John Kelly were also invited but won't attend.
Mr Biden will be sworn in as president at 4am AEDT.
