US First Lady Melania Trump steps off a plane upon arrival at McAllen Miller International Airport in McAllen, Texas on June 21, 2018.
But it came after 2,300 children were split from their parents, some in circumstances where border agents informed the parents they were taking the children to get a bath.
The Daily Mail first reported the jacket, which was spotted by the press traveling with the first lady but impossible to read without a long-range camera lens.
She later inspected the detention facility's schoolroom and chatted with about 20 young girls and boys who had school folders on their desks. "Nice to meet you", she said as she left one classroom. During her visit, Mrs. Trump toured a children's shelter and attended a briefing on the status of immigrant children.
Students welcomed her with a large paper American flag taped to a wall that they'd signed.
Images and recordings of distressed children held in enclosures akin to cages have sparked global fury.
She was greeted by Upbring CEO Dr Kirk Senske, who said: "We treat them like our own children".
