White House chief of staff Ron Klain sided with teachers unions on Tuesday against reopening schools without providing additional funds to allow for better compliance with social distancing protocols — despite several reports published by the Centers for Disease Control and Prevention suggesting that a viable path to reopening schools exists.

“What that study in Wisconsin from the CDC showed was that 17 rural schools that got a sizable grant from a private foundation to put in the kinds of safety measures they need — students in very small pods, classes of about 11 or 12, distanced, in a rural area — they could go to school safely,” Klain told CNN. “Gov. [Jared] Polis is a great leader in this field, you know, he’s done a lot, but in other states, we haven’t seen those kinds of investments.”
