Back to school: Omicron edition

Months after Delta threatened the fall back-to-school ritual, COVID-19 is again complicating kids' return to the classroom.

Why it matters: While government officials worked to convince school administrators and parents over the last several days that kids could safely get back to in-person learning after the holidays, the reality on the ground amid the spread of Omicron is much more complicated.

What they're saying: "I still believe very firmly and very passionately, not only as an educator but as a parent, that our students belong in the classroom and that we can do it safely," Education Secretary Miguel Cardona said on CBS' "Face the Nation" on Sunday.
