At a CNN town hall on Tuesday evening, President Biden said his goal is to open the majority of K-8 schools by the end of his first 100 days in office. Asked to clarify what he meant by "open," Biden said "I think many of them five days a week. The goal will be five days a week" in person.

He said he would focus on K-8 schools because they're the "easiest to open" due to the relatively low transmission rate of the coronavirus between children.

His response contradicts what White House Press Secretary Jen Psaki said last week — that the president's goal was to have the majority of schools open at least one day a week in person in the same time frame, without specifying K-8. Biden dismissed the discrepancy as a "mistake in the communication." Psaki has also said Biden eventually wants schools open five days a week, without giving a time frame.

The topic of COVID-19 was a persistent theme throughout Tuesday evening's socially distanced Milwaukee town hall event, which included about 50 attendees from the state of Wisconsin.
