'The Expert' Barron Trump wears funny T-shirt, plays with fidget spinner during White House move

Nearly five months after President Donald Trump's inauguration, Melania Trump and son Barron officially moved into the White House on Sunday.

The youngest of the Trump children, Barron, was photographed wearing a T-shirt that read "The Expert" and playing with a fidget spinner aboard the Marine One with his parents and several pieces of luggage.

Barron and his mother have arrived in Washington to stay after residing in Trump Tower in New York City for the past several months while the 11-year-old finished up the academic year.

The middle schooler's T-shirt has emerged as the subject of intense speculation online, as some Trump supporters say the shirt refers to the president's discussion of his son's tech savviness with computers and others argue otherwise.

"I have a son, he's 10 years old. He is so good with these computers. It's unbelievable," Trump said in a September debate with Hillary Clinton during a discussion of cyber security. "The security aspect of cyber is very, very tough."

But many online aren't buying the idea.

Some think the middle schooler was trolling his father.

And others took the shirt's message as an indication of the young Trump's new role in the White House, possibly in national security.
