Former Vice President Joe Biden on Tuesday fired back at President Trump for sharing a tweet that mocked Biden for wearing a mask during a Memorial Day event, calling him an "absolute fool." The Centers for Disease Control and Prevention has recommended that people wear masks to slow the spread of coronavirus, but Trump has opted out of wearing a face covering during visits to factories, despite the companies requiring masks for the safety of their employees. This is irresponsible, Biden told CNN's Dana Bash, and Trump's refusal to listen to health experts is "costing people's lives." Presidents, Biden added, "are supposed to lead, not engage in folly and be falsely masculine."
