Mr. Trump is spending his first Christmas in office with his family at his estate and private club in Palm Beach, Florida.

Meanwhile, NATO soldiers in Kabul today donned Santa hats and celebrated the holiday with a roast turkey dinner.

In the day's other news, Israel's prime minister praised Guatemala's plan to move its embassy in the country to Jerusalem. The Central American nation is the first to follow President Trump's lead on the change. Guatemala was among a small handful of countries that voted against a United Nations resolution denouncing Mr. Trump's recognition of Jerusalem as Israel's capital.

It wasn't immediately clear how the change would impact the U.S. contribution. But Ambassador Nikki Haley said she wouldn't let the generosity of the American people be taken advantage of.

Election officials in Russia have banned opposition leader Alexei Navalny from running for president. Navalny had been convicted in a fraud case, which was seen by outside observers as a way to sideline him. After the decision, Navalny called for a boycott of the election in March.
