Chelsea Clinton, the former first daughter, has jumped to the defence of Barron Trump after a report criticised the way he dressed.
While his mother Melania receives most of the attention in the family when it comes to fashion, the 11-year-old has caused a stir of his own for his style choices.
Two months ago, President Donald Trump's youngest son set social media alight by wearing a blue T-shirt that said "the Expert" on the front.
And on Sunday night, the "first boy" caused a stir again when he returned to the White House with his father and mother wearing another J. Crew T-shirt that bore the phrase "On your mark tiger shark", along with an image of a shark.

While many social media users praised his style, right-wing website The Daily Caller was not impressed.
"Barron looked like he was hopping on Air Force One for a trip to the movie theater," an article said, under the headline "It’s High Time Barron Trump Starts Dressing Like He’s In the White House".
It concluded: "The youngest Trump doesn’t have any responsibilities as the president’s son, but the least he could do is dress the part when he steps out in public."
Ms Clinton, who lived in the White House from the age of 12 to 20, tweeted a link to the article, saying: "It's high time the media & everyone leave Barron Trump alone & let him have the private childhood he deserves."

It is not the first the 37-year-old daughter of Hillary and Bill Clinton has leapt to the defence on Barron.
After the young boy was mocked by comedians and social media users for looking bored on inauguration day, Ms Clinton, a friend of Barron’s sister Ivanka, said the boy should be allowed to “be a kid”.
“Barron Trump deserves the chance every child does - to be a kid,” she tweeted on Sunday.
Barron Trump is the first boy since John F Kennedy Jr to live in the White House.
He has spent his life living in Trump Tower, where he has a whole floor to himself – close to his grandparents. He speaks Slovenian with them and with his mother.
He was thrust into the spotlight on election night when he stood alongside his father as he celebrated his victory. Since then, the media attention has grown, even apparently becoming a manga character in Japan.
