Donald Trump said Sunday that he is cured of COVID-19 just over one week after diagnosis as he claims he is now 'immune' from the virus.'Once you recover, you're immune,' Trump told Fox News' Maria Bartiromo on 'Sunday Morning Futures' in a phone interview. 'Now you have a president that's immune.' Moments after the interview he tweeted: 'A total and complete sign off from White House Doctors yesterday. That means I can't get it (immune), and can't give it. Very nice to know!!!'He told Bartirormo that the newfound immunity comes with a 'protective glow.''So now you have a president who doesn't have to hide in his basement,' he added, repeating a criticism he had of Joe Biden, who largely campaigned from a basement television studio in the midst of the coronavirus pandemic.Biden has since hit the campaign trail, donning a mask.'I'm not on any medication. And the medications that I did take were standard, routine.' Trump's top physician Dr. Sean Conley has said Saturday night that the president is no longer at risk of transmitting coronavirus. He did not say explicitly at the time whether Trump had yielded negative test results for COVID-19. Last week, Conley revealed the president has tested positive for antibodies for the virus. In a memo released on Saturday night, the White House physician said Trump meets the Centers for Disease Control and Prevention criteria for safely discontinuing isolation.By 'currently recognized standards,' Conley continued, Trump is no longer considered a transmission risk. The president cleared the air Sunday since Conley's note did not say whether Trump still has coronavirus. Bartiromo asked if the statement means he has tested negative for the virus. 'Not only that, it seems like I'm immune,' Trump said. 'It looks like I'm immune for, I don't know, maybe a long time, maybe a short time. It could be a lifetime. Nobody really knows.'Conley's diagnosis comes as the president prepares to resume campaign rallies and other activities - starting Saturday when he held a 'peaceful protest' at the White House. Some medical experts had been skeptical that Trump could be declared free of the risk of transmitting the virus so early in the course of his illness. Just 10 days since an initial diagnosis of infection, there was no way to know for certain that someone was no longer contagious, they said.The memo followed Trump´s first public appearance since returning to the White House after being treated for the coronavirus. Hundreds of people gathered Saturday afternoon on the South Lawn for a Trump address on his support for law enforcement from a White House balcony.Trump took off a mask moments after he emerged on the balcony to address the crowd
