Betsy DeVos is getting a lot of security from the U.S. Marshals Office.

She’s the secretary of education. Yet her security detail is running up a significant tab, nearly $20 million through September 2019.

I can understand such heavy security for, oh, the Drug Enforcement Agency boss, or the secretary of state, or the secretary of defense, the CIA director, the FBI director, the attorney general, the director of national intelligence, the Joint Chiefs of Staff, the United Nations ambassador … and oh yes, the president and vice president of the United States of America.

But the education secretary? The individual charged with administering our nation’s public school systems?

DeVos has been heckled by protestors. The Justice Department ordered the protection after such heckling.

But, man, that’s a lot of money to spend guarding the nation’s public school boss. I would like to know what, precisely, we’re paying for.
