CONCORD, N.H. (AP) — Pressure is building on school systems around the U.S. to reopen classrooms to students who have been learning online for nearly a year. The debate is pitting politicians against teachers who have yet to be vaccinated against COVID-19. In Chicago, there’s so much rancor that teachers are on the brink of striking. In California, a frustrated Gov. Gavin Newsom implored schools to find a way to reopen. In Cincinnati, some students have returned to their classrooms after a judge threw out a teachers union lawsuit over safety concerns.
