On which topic did Joe Biden rely on science to support his decisions?

Former Vice President Joe Biden emphasized the importance of approaching the coronavirus pandemic with caution and touched on his running mate selection process during a wide-ranging question-and-answer session with reporters on Tuesday.

The remarks, which were made in Wilmington, Del., followed Biden's address unveiling his plan to combat racial inequality in the economy

When asked whether professional sports should be allowed amid the pandemic, Biden said, "They should just follow the science."

"It seems to me that it’s probably not going to be able to happen based on what the leagues themselves are saying,” he said referring to a recent outbreak of the virus that resulted in MLB suspending the rest of the Miami Marlins' season on Tuesday. "I mean you have the Marlins saying, we can't do it. So I think they should probably just follow the science."
