President-elect Donald Trump on Sunday confirmed The Post’s exclusive report that soon-to-be first lady Melania Trump is staying behind at Trump Tower in Manhattan with their son, Barron, when he heads to the White House.

Trump said his wife and son would move to Washington at some point.

When reporters asked when his wife and young son might be joining him, Trump replied, “Very soon. Right after he finishes school.”

Earlier Sunday, Trump spokesman Jason Miller said, “There’s obviously a sensitivity to pulling their 10-year-old out of school in the middle of the school year. A more formal statement will be coming in the future.’’

Trump will be sworn into office Jan. 20.

Barron currently attends an exclusive prep school on the Upper West Side.
