school or wherever. you should stay home until you get a negative test. i wish there were more of these tests. more are on the way. make sure we are ramping up production of these tests. there's going to be a shortage in some of the reagents needed to make those tests and need to ramp up that supply chain so we have these in our arsenal ready to end omicron but also ready to fight that next variant. >> let me get to the next headline, biden officials divided on message over n-95 masks for all, the cdc stopping short of recommending people should choose some masks over others. some may choose to wear an n 9 and kn-95 masks because they offer the best protection. is this the right move? why not swap the word should for may if the cdc believes those masks offer better protection? >> you know, i'm disappointed in the messaging still coming out of the cdc on testing and on n-95 and appropriate mask
