about keeping our babies safe. >> one parent of what they're arguing to the court, let me read it in part, this order will force thousands of unvaccinated public school employees to lose their jobs, they argue, while other municipal employees, including those who have significant contact with children, are allowed to opt out of the vaccine mandate through weekly covid-19 testing. they're essentially arguing they're being singled out when other city employees have a testing option. are they? >> no. we don't feel that way. and, you know, we also have, you know -- we are responsible for over a million students and we have elementary school students who are not eligible for vaccination, and so we have to do everything in our power to wrap a bubble of protection around our children and keep them safe. >> school is already under way. this is one big step towards what you have promised. you have given a large heads-up this was coming. today is that final day to get that vaccine. good to see you, chancellor. thank you very much. >> thank you so much.
