Valerie Strauss calls out Attorney General Jeff Sessions as “the worst teacher of the week.” He might be the worst teacher of the year.

Speaking to a conservative group of high school students, he did not stop them when they chanted, “Lock her up.” He laughed and may have joined them.

Strauss writes:

“Whatever he actually thought he was doing, this is what he did not do: educate the crowd about the fact that Clinton was never charged with any crimes, and that U.S. presidents don’t jail their opponents because they don’t like them.

“He could have given them a basic lesson in American jurisprudence. He didn’t.

“He could have done what John McCain did in 2008 during a town hall meeting in Minnesota when people in the crowd leveled racial and ethnic attacks against Barack Obama. McCain told them they were wrong. When one of his own supporters said he was scared of Obama, McCain said: “I have to tell you: He is a decent person and a person you don’t have to be scared of as president of the United States.”

“When another of McCain’s supporters said Obama was an “Arab,” meant by the backer as a pejorative, McCain took the microphone from her and said: “No, ma’am. He’s a decent family man, citizen, that I just happen to have disagreements with on fundamental issues, and that’s what this campaign is all about.”

“Sessions didn’t act anything remotely like that. Which makes him the worst teacher of the week — even though it is only Tuesday.”
