Democratic nominee Joe Biden said in an NBC News town hall Monday night he was "very happy" that President Donald Trump "seems to be coming along pretty well."
But, he said, he was concerned by Trump's tweet that Biden characterized as telling Americans, "don't be so concerned about this, essentially."
"Don’t be afraid of Covid. Don’t let it dominate your life," Trump had tweeted hours before he departed from the Walter Reed medical center.
"You have about 1,000 people a day getting the coronavirus. It's a significant concern. I hope no one walks away with the message thinking it's not a problem," Biden said. "It's a serious problem. It's an international pandemic."
He said he hopes that the message from Trump's battle with the virus will be that Americans should wear masks and follow social distancing guidelines.
Biden said Trump bears responsibility for contracting coronavirus because he flouted the Centers for Disease Control and Prevention's guidance.
"Anybody who contracts the virus by essentially saying, masks don't matter, social distancing doesn't matter, I think is responsible for what happens to them," Biden said of Trump. Holding up a mask, he said, "I view wearing this mask, not so much protecting me, but as a patriotic responsibility."
