The President of the United States spent three nights in the centre after testing positive for coronavirus.
Mr Trump seemed in good spirits, announcing his discharge from the hospital in a tweet.
He wrote: “I will be leaving the great Walter Reed Medical Center today at 6:30 P.M.
“Feeling really good! Don’t be afraid of Covid. Don’t let it dominate your life.
“We have developed, under the Trump Administration, some really great drugs & knowledge.
“I feel better than I did 20 years ago!”
Footage of Mr Trump leaving the centre showed him wearing a face mask and walking towards reporters waiting at the end of the stairs.
One journalist is heard asking him: “Do you think you might be a super-spreader, Mr President?”
