Joe Biden said he will wear a mask in public, drawing a contrast between President Donald Trump and himself amid the coronavirus pandemic. On Sunday, the former vice president and current de facto Democratic presidential nominee emphasized one phrase repeatedly: “Follow the science.” “It’s important to follow the science. Listen to the experts. Do what they tell you,” he said on ABC’s “This Week." "So If I go out in public — and I haven't gone to commercial places of late, I haven't gone to my local church, etc. ... My generic point is, you should follow the science.“
