Biden and his shifting goalposts on schools

How do you define success when it comes to reopening schools in the pandemic? President Joe Biden and his aides are having difficulty settling on an answer to that question.

At his town-hall forum Tuesday night, Biden denied that his administration ever thought one day of classroom instruction a week would be enough to declare victory in his pledge to get most schools for younger children open by spring. That’s dubious, given the conflicting account provided by his press secretary last week.
