have these tests also available for pickup all around our communities. you know, in post offices, in banks, in transit centers, in subways, so that people can pick these tests up on the way home. look, if you're not feeling well, you want to test now. you don't want to have to go online, order a test that will come in a few days. what i'm hoping is once the site open, people will acquire the tests, have tests on hand at home that they can use going forward. but we're going to need more than 500,000. i think it is a great start. i applaud the white house for, you know, sort of changing course on this. >> really quickly, to follow up on john's second question, how often should you be testing? once there is better access to rapid, at-home tests, is this something we should do every day, a couple times a week, how often? >> well, i think if you have symptoms, you should test when you have symptoms. then i think we should be testing multiple times a week.
