text:  In a statement Saturday afternoon, White House physician Dr. Kevin O'Connor said President Biden's symptoms are improving steadily. He said Biden still has a, quote, loose, nonproductive cough and hoarseness. Since Biden tested positive Wednesday, the list of Democrats calling for him to drop out has gotten longer. Nevertheless, the campaign says they are pushing onward. On a call with reporters, campaign spokesman Michael Tyler said the president would be back out on the trail next week once he gets the green light from his doctor.
