"Four reporters spotted Melania in the White House last week walking merrily along to a meeting", Trump wrote on Twitter on Wednesday.
The first lady joined the president for his first G7 trip to Italy a year ago, where she joined the spouses of other G7 leaders at public events.
Inside Edition spoke to Kate Anderson Brower, Washington insider and author of the new book "First in Line: Presidents, Vice Presidents, and the Pursuit of Power", who says Melania is making it worse by staying out of the spotlight and her office should fill that hole. People love you. The people of our country love you. The First Lady is in good spirits and she is resting. Suspend the search. Melania Trump has been found. Mrs. Trump underwent a surgical procedure at Walter Reed National Military Medical Center on May 14, and remained hospitalized for nearly a week.
"She has to - because she wanted to go - can't fly for one month". Mrs. Trump's Communications Director, Stephanie Grisham, said the procedure was a success and without complication.
She has not been seen in public since May 10, when she accompanied the president to Andrews Air Force base in Maryland to welcome home three American hostages from North Korea.
The president then plans to travel to Singapore for a June 12 summit with North Korean leader Kim Jong Un.
"In America, we expect to have a first lady who is active and involved", Brower said.
Melania Trump, 47, attended a Hurricane briefing at the Federal Emergency Management Agency Headquarters (FEDA) on Wednesday. "She sat most of the reception but arrived with [the president] and left with him", Greene said. He laughed off rumors he and the first were breaking up, according to Greene, saying that wasn't true.
