President Donald Trump’s wife Melania and their 11-year-old son Barron have officially moved into the White House. She and the boy had been living at the family’s home at Trump Tower in New York so Barron could finish out the year at his current school. In keeping with American tradition, President Trump moved to Washington, DC immediately after he took office in January. Since then, he has lived in the White House -- one of the most famous buildings in the world. Melania Trump announced the move Sunday on Twitter. She wrote, "Looking forward to the memories we'll make in our new home! #Movingday.” Her announcement included a picture of the Washington Monument as seen from a room inside the White House. The president spent last weekend away from the White House. He went to one of his golf properties in the state of New Jersey.
