US President Donald Trump said he will leave the White House if the Electoral College votes for Democratic President-elect Joe Biden.
In the nearest he has come to a concession, Republican Trump said if Biden is certified the election winner by the Electoral College he will depart the White House. Biden is due to be inaugurated on January 20.
The Electoral College is due to meet on December 14.
Trump made the comments at the White House after speaking to US troops during the traditional Thanksgiving Day address to American servicemembers.
Biden won the November 3 presidential election with 306 Electoral College votes - many more than the 270 required - to Trump's 232. Biden also leads Trump by more than 6 million in the popular vote tally.
Trump has so far refused to concede the election and continues to claim without evidence that the voting was marred by widespread fraud, and that he had won it.
