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 Jan. 20.
The Electoral College is due to meet on Dec. 14.
Trump made the comments at the White House after speaking to U.S. troops during the traditional Thanksgiving Day address to U.S. service members.
Biden won the Nov. 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 election was marred by widespread fraud, and that he and not Biden won it.
