biden administration will be ready if the u.s. is hit with yet another wave. joining us now is dr. tom inglesby, senior adviser to the white house covid response team and john hopkins bloomberg school of public health. doctor, thank you for being with us this morning. i want to talk about testing and masking. testing first. can you tell us what you are making of the testing industry? taking a step back for a moment when we started the administration there were no rapid tests on the market. and over the past year, we've seen the supply of rapid tests grow dramatically. we now have a very strong market. the pharmacy stocks are now ready for people to buy these tests. we have tests now covered by private insurance. and hundreds of millions of tests are now either delivered to americans's homes or on their way to americans's homes.
