 NPR's Eder Peralta in Mexico City, John Rewich in Beijing, and Charles Mainz in Moscow. Thanks to all three of you. Thank you. You bet. President Biden has tested positive for COVID. He was in Las Vegas campaigning. The White House said he developed a runny nose and a cough, so he took a COVID test and got the news. Now he's back at his beach house in Delaware, where the White House says he'll continue his normal duties. But this comes at a time when very little in his campaign is actually normal. The health of this president and his ability to seek a second term is definitely under the microscope.
