Two weeks after undergoing a kidney procedure — and almost three weeks afterher last public appearance— First LadyMelania Trumpis back to work at the White House and “doing really well,” her spokeswoman, Stephanie Grisham, tells PEOPLE.

“She’s been involved in several internal meetings with staff all last week, and that continues this week,” Grisham says. “We’ve been going over initiatives and other long term planning for events such as the Congressional Picnic and 4th of July.”

The first lady, 48, has not been seen in public in 19 days. She was lastspotted on Thursday, May 10, when she stood next to her husband, PresidentDonald Trump, to welcome home three Americans at Joint Base Andrews, according toThe Washington Post.

Four days later, on May 14, the first lady’s office made the surprise announcement that she had undergone a“successful” kidney procedure, but would remain hospitalized for the remainder of the week.

Sincereturning home on May 19, the first lady has been completely out of the spotlight, which thePostnotes is an “unusually long absence” for even the most private of presidential spouses.

Asked about the first lady’s health on Friday morning, the president told reporters gathered at the White House that his wife was inside.

“She’s doing great. Right there,” Trump said, pointing up toward the second floor of the White House from the south entrance. “She’s doing great. She’s looking at us, right there.”

But as reporters turned to follow his outstretched finger, they saw no sign of his wife, reports thePost.

Grisham did not specifically say when Mrs. Trump would be seen again, so her return to public life remains a mystery. It’s unclear whether she’ll attend a White House Sports and Fitness Day event that the president is expected to participate in on Wednesday.
