Trump is spending the holidays at his Mar-a-Lago estate in West Palm Beach. He arrived on Dec. 20 and is scheduled to return to Washington on Sunday.

Mar-a-Lago is located a short drive from Trump International Golf Club, which the president has visited most days during his vacation so far.

The White House only infrequently provides information on the president's activities or his playing partners when he visits one of his golf clubs.

During his campaign for the White House, Trump was a fierce critic of how much time then-President Obama spent golfing.
