First lady Melania Trump underwent kidney surgery Monday at Walter Reed National Military Medical Center near Washington, DC, according to a statement from her office.

Trump had been experiencing an issue with her kidney that her office described as benign but requiring medical attention.

“This morning, first lady Melania Trump underwent an embolization procedure to treat a benign kidney condition. The procedure was successful, and there were no complications,” the first lady’s communications director, Stephanie Grisham, said in a statement.

“Mrs. Trump is at Walter Reed National Military Medical Center and will likely remain there for the duration of the week. The first lady looks forward to a full recovery so she can continue her work on behalf of children everywhere,” Grisham wrote.

President Donald Trump remained in the White House during Melania Trump’s surgery. He is expected to visit the hospital shortly, Grisham said. Trump, who turned 48 last month, entered Walter Reed in nearby Bethesda, Maryland, on Monday morning.
