Melania Trump expected to remain hospitalized for rest of the week

White House officials say first lady Melania Trump is expected to remain hospitalized for the rest of the week following a “long-planned” procedure to treat a benign kidney condition.

The 48-year-old had an embolization procedure Monday morning at Walter Reed National Military Medical Center. President Donald Trump visited her later Monday and tweeted that the procedure was “successful”.

Vice President Mike Pence described the procedure as “long-planned.”

Urologists say the most likely explanation for the procedure is a kind of noncancerous kidney tumor called an angiomyolipoma, which isn’t common but tends to occur in middle-aged women.
