EPA Administrator Johnson did not attend today's hearing in California that discussed EPA's denial of a waiver to limit GHG emission levels. According to Senator Susan Boxer (D-CA) she invited him to explain the denial and he declined. She then asked if he would send another EPA member and the documents that were used as he made his decision, and again received a negative response. Among the witnesses that testified at the hearing were California's Attorney General Brown and CARB Chairman Nichols.
