WASHINGTON • The White House has two new occupants: United States First Lady Melania Trump and her son Barron have finally moved into 1600, Pennsylvania Avenue.

Six months after US President Donald Trump arrived, the former model, who was born in Slovenia, and the couple's 11-year-old son have joined him.

The pair had previously stayed in New York so that Barron could complete the school year. He is expected to attend St Andrews Episcopal School, just outside Washington, in the 2017-2018 session.

Mrs Trump and Barron, as well as the First Lady's parents, had earlier flown with the President on Air Force One for the short flight to Joint Base Andrews near Washington from Bedminster, New Jersey, where Mr Trump had spent the weekend at his golf course.

After arriving at the White House, Mrs Trump tweeted a picture from a window looking on to the South Lawn and the Washington Monument. She wrote: "Looking forward to the memories we'll make in our new home! #Movingday."

Mrs Trump is the first First Lady in modern history to delay her arrival in Washington after an election win.

"My husband is travelling all the time," she said after the election last November, when she announced she would remain in New York.

She added: "Barron needs somebody as a parent, so I am with him all the time."

Mr Trump had been living alone in the vast, private quarters of the White House.

The First Lady has mostly kept a low profile since her real estate mogul husband became president.

Arguably, her biggest public outing came last month when she and Mr Trump visited the Middle East and Europe on a trip that the White House later praised as a resounding success.
