Melania and Barron have moved to the White House - here's the $40,000 private middle school Barron will attend this fall

Melania and Barron Trump moved into the White House on Sunday, a move they had delayed so that Barron could finish the year at his New York City-based day school rather than moving to Washington, D.C. right away.

Barron attended Columbia Grammar and Preparatory School, an elite school located in the Upper West Side of Manhattan that runs students about $47,000 a year.
