WASHINGTON • United States President Donald Trump said on Thursday that he will leave the White House if the Electoral College votes for President-elect Joe Biden, the closest he has come to conceding the Nov 3 election, even as he reiterated his unfounded claims of massive voter fraud.

Speaking to reporters on the Thanksgiving holiday, the Republican Mr Trump said that if the Democrat Mr Biden - who is due to be sworn in on Jan 20 - is certified the election winner by the Electoral College, he will depart from the White House.

But Mr Trump said it would be hard for him to concede under the current circumstances, and declined to say whether he would attend Mr Biden's inauguration.

The electors are scheduled to meet on Dec 14.

"This election was a fraud," Mr Trump insisted, while offering no concrete evidence of such voting irregularities.

Mr Biden and Mr Trump both stayed close to home to celebrate Thanksgiving on Thursday as the coronavirus pandemic raged across the country.

Mr Biden spent the holiday in the small seaside town of Rehoboth, Delaware, where he and his wife Jill have a vacation home. The Bidens are hosting their daughter Ashley and her husband Howard Krein for the holiday meal.

The former vice-president, appearing with his wife in a video message posted to his Twitter account on Thanksgiving, said his family typically holds a large gathering on the island of Nantucket, off Massachusetts.

However, they would remain in Delaware this year "with just a small group around our dinner table" because of the pandemic.

In the presidential-style address to a nation that has lost more than 260,000 lives to the coronavirus, the Democratic President-elect said Americans were making a "shared sacrifice for the whole country" and a "statement of common purpose" by staying at home with their immediate families.

Mr Trump often likes to celebrate holidays at his Mar-a-Largo resort in Florida.

But on Thursday, he remained in the Washington area, spending part of the morning at his Trump National Golf Club in Virginia, where he played a round of golf.

It was a far cry from last year, when he made a surprise visit to Afghanistan and served turkey to US troops before sitting down to eat Thanksgiving dinner with them.

This time, Mr Trump spoke by video link from the White House to members of the military.
