An October 7 letter from Senate Environment and Public Works Ranking Member David Vitter (R-LA) to President Obama urged the administration to send an official to testify at an upcoming committee hearing on climate change. Chairman Barbara Boxer (D-CA) previously announced that she intends to hold a hearing this month on climate change, specifically the President’s Climate Action Plan, the recent Environmental Protection Agency new source performance standards, and the U.N. Intergovernmental Panel on Climate Change’s Fifth Assessment Report, but has not yet invited anyone from the administration to testify.
