"It would be a catastrophic thing to do for our people and for our economy, if we sent people back to work just as we were beginning to see the impact of social distancing take hold, only to unleash a second spike in infections" Biden said via a virtual briefing from Wilmington, Delaware.

U.S. President Donald Trump pressed his case on Tuesday for a re-opening of the U.S. economy by mid-April despite a surge in coronavirus cases, downplaying the pandemic as he did in its early stages by comparing it to the seasonal flu.
