It remains unclear when her next public appearance will be.
Other than her message chiding the media, the White House has been largely silent on the first lady's status.
However, her recent absence has been astonishing even by her own low-profile standards.
On May 14, the White House announced that the first lady had been sent to the Walter Reed National Military Medical Center to undergo an embolization procedure to treat a benign kidney condition. "She was hospitalised for nearly a week and is now home and recovering".
Anyway, Melania, though, and made a statement, to show the public not in a hurry.More news: 'Catalan government's first day at work'
There's the one about special counsel Robert Mueller having her under questioning for hours and hours. She had a formal dinner and took in a performance by La Scala Philharmonic Orchestra at the Ancient Theatre of Taormina.
But did Melania really write the tweet? "The first lady looks forward to a full recovery so she can continue her work on behalf of children everywhere".
Donald's own attempt to quell the chatter also backfired. Right there. She's doing great. During the trip, the first lady made an global splash for her glamorous fashion choices, such as a $51,000 Dolce & Gabbana jacket and a glittering silver dress and shoes.
Whatever the reason for her lengthy seclusion, those starting to suspect that the First Lady has disappeared altogether will at least have their concerns put to rest. The reception is not open to the press, the White House added.
Melania has regularly accompanied her husband to big occasions and earned praise for playing a flawless host to French President Emmanuel Macron and his wife Brigitte during the Trump administration's first state honour organised in late April.
