US Senate at loggerheads over clean energy legislation

Today, the US Senate Environment and Public Works Committee held a hearing to look at developing new clean energy legislation that would impact global warming.
Committee members heard from the heads of the EPA and the departments of Energy, Agriculture and the Interior.
But the real tension came from the Senators themselves, with Democrats accusing Republicans of being reluctant to move forward with clean energy  and Republicans accusing Democrats of favoring higher energy taxes and trumping up charges of climate change. FSRN´s Karen Miller has more.
