PSAKI: "Well, the guidance is very clear, which is that we recommend masking in schools. That is the recommendation from the CDC. It is also true that at some point, when the science and that data warrants, of course, our hope is that that’s no longer the recommendation, and they are continually assessing that. But the guidance is very clear. It is also true that has always been up to local school districts to make determinations about how to implement these policies."
