Here is a video of Rep. Joe Barton (R-TX)–the ranking member on the House Energy & Commerce Committee asking a question of Nobel Prize winning Energy Secretary, Dr. Steven Chu. He asked where oil comes from and was puzzled by the answer.
It's really shocking that he would ask an eminent scientist a question requiring a long answer giving him only 6 seconds and then try to badger him about whether Alaska was hot at the time the oil was produced. Was this a dig at the idea of global warming I guess? Strange.
