The bottom line is if you look at pediatric vaccinations where we have mandates in place, vaccines are a requirement to go to school.

I think the downside of this mandate in terms of hardening positions and taking something that was subtly political and making it overtly political could outweigh any of the benefits that we hope to achieve.

Herd immunity is achieved at 93 to 95%. We're well below that in most parts of the country.

I think that’s where the President could have exerted more leadership in the White House.
