Biden tests positive for COVID-19, has 'mild symptoms', White House says

US President Joe Biden tested positive for Covid-19 while traveling Wednesday in Las Vegas and is experiencing "mild symptoms" from the virus, the White House said. Press secretary Karine Jean-Pierre said Biden will fly to his home in Delaware to “self-isolate". Biden is under pressure to abandon his reelection bid due to concerns about his age following a poor debate performance at the end of June.
