Biden, 81, sparks mass confusion with bizarre tweet about being 'sick' after testing positive

The 81-year-old president was forced to cancel a speech in Las Vegas during a campaign trip after a taking a test when he started getting a runny nose and coughing. As he slowly boarded Air Force One maskless for the flight back to the East Coast to begin isolation, he gave a thumbs' up and said: 'I feel good'. The White House physician said Biden was feeling 'general malaise' and will now self-isolate in Delaware . The West Wing added that the president is vaccinated and boosted, and took a dose of Paxlovid on Wednesday afternoon. Earlier on Wednesday he was speaking to supporters at a restaurant while Democrats reignited calls for him to step down from the 2024 presidential race. In an interview this week he said he would only drop out if doctors told him to and he had a medical that made it necessary.
