First lady Melania Trump was released from the hospital Saturday morning, after undergoing a kidney procedure earlier in the week, and returned to the White House “in high spirits,” an aide said.

Trump, who spent five nights at Walter Reed National Military Medical Center in Bethesda, was “resting comfortably,” Stephanie Grisham, the first lady's communications director, said in a statement.

The first lady underwent an embolization procedure Monday to treat a benign kidney condition. President Trump visited her three times during the week and had tweeted that she was doing well.

“Our office has received thousands of calls and emails wishing Mrs. Trump well,” Grisham said, “and we thank everyone who has taken the time to reach out.”

President Trump tweeted Saturday afternoon that his wife was home and doing “really well.”

“Great to have our incredible First Lady back home in the White House. Melania is feeling and doing really well. Thank you for all of your prayers and best wishes!” he wrote.
