you are not mandating the vaccine for everyone. there's this weekly testing option out there. there's also not everyone. the postal service is not included. when it comes to teachers, you are asking governors to do it. i was personally shocked the other day, in new york city, with these incredibly high vaccination rates, teachers who are about to teach kids who aren't vaccinated are only 72% vaccinated. it was shocking. obviously, i don't know, is it the unions you feel like you are not able to mandate for the postal service or teachers? >> we are doing it everywhere we can. the postal service is an independent agency. teachers, the president is doing it where he can within the federal government. all teachers that teach as part of the department of defense school system and department of interior. the president is insisting on a vaccine of all teachers across the country. about 90% of teachers and staff at schools are vaccinated. that should be 100%.
