for everyone in the u.s. to start wearing them if they wanted to? >> i think so, jake, but this is a remarkably hard question to still answer. even as reporters going on, looking at all the various sites, looking at what the cdc says availability is but also nonprofits like project n95 which is a great site people should go to if they're trying to find masks and make sure the masks are real masks, not counterfeit masks. but you're right. still, it's not clear, dr. fauci says there should be enough of these masks now. the n95 masks. and by the way, we've talked about this. but n95 masks like this one, you want to make sure that they are legitimate masks. there's all sorts of different ways to do this. various websites will tell you how to do it. but one thing is if they have the loops around the back of the head, that's a pretty good sign you'll get a mask that has a more snug fit as opposed to just the ear loops. just a little tip there in terms of trying to figure out which mask works.
