U.S. Education Secretary Betsy DeVos has visited all kinds of schools since she took office last year: district-run, charter, private, religious — even a school located in a zoo.

But one kind of school has been left out, she said Sunday on 60 Minutes: schools that are struggling.

It was a curious admission since DeVos has built her policy agenda on the argument that vast swaths of American schools are so low-performing that their students should be given the choice to leave. That argument, DeVos conceded, is not based on any firsthand experiences.

The exchange occupied just a few seconds of the nearly 30 minutes that DeVos spent on television Sunday and Monday, including interviews on Fox and Friends and the Today Show. The appearances followed several school-safety proposals from the White House Sunday, including paying for firearms training for some teachers.
