U.S. EPA Administrator Stephen Johnson appeared before Senate Democrats today to defend his decision to deny California’s auto-emissions waiver. Johnson stood his ground while senators assailed his decision as in the pocket of special interests, logic-defying, “shameful,” “outrageous,” “irresponsible,” and “unconscionable.” Responded Johnson, “I evaluated all the data, I made the decision, it’s the right decision. I was not directed by anyone to make the decision.” Wait — is Johnson the Decider? Now we’re all confused. Sen. Barbara Boxer has said she will introduce a bill that would reverse Johnson’s decision.
