Top health advisor to President-elect Biden says national lockdown is a possibility

Michael Osterholm, a top health adviser to President-elect Joe Biden, says a four to six-week national lockdown is a possibility.
Osterholm, the director of the Center for Infectious Disease Research, says the U.S. can withstand one financially.
Osterholm says the personal savings rate is up, and there is a "big pool of money" that could support the economy during that time.
Biden has promised to listen to scientists on how to stop the pandemic, but has not proposed such a measure himself.
