WASHINGTON — Melania Trump made another secret trip Tuesday, though she stayed a little closer to home.

The first lady visited with wounded service members at Walter Reed National Military Medical Center after traveling to the Washington-area hospital.

The White House did not publicly announce the trip until after she had arrived.

Stephanie Grisham, the first lady’s spokeswoman, tweeted that Mrs. Trump was visiting with “combat injured service members & their families.”

Mrs. Trump tweeted later Tuesday that she had a “wonderful visit” and offered thanks to the “many dedicated service members & medical staff who take such good care of our men & women in uniform.”

The Walter Reed stop followed recent separate trips by the first lady that were not publicized until she arrived at her destinations in Texas and Arizona along the U.S.-Mexico border.

She visited migrant children who have been separated from their families under her husband’s crackdown on illegal immigration.

The first lady also spent five days as a patient at Walter Reed hospital in Bethesda, Maryland, following kidney surgery in May.
