Donald Trump has said he will leave hospital on Monday evening after a three-day stay to treat symptoms of Covid-19. The president tweeted: “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!”
