Members made opening statements for the markup on the Senate Climate Change and Energy Bill. In an effort to address Republican concerns, Environment Committee Chair Barbara Boxer extended the deadline for amendments and invited the Environmental Protection Agency to attend the afternoon session. Republican Senator George Voinovich attended the session and spoke for Republican committee members who boycotted today's mark up of climate change legislation. He laid out the Republicans' objections to the markup session and why they are refusing to participate. He became emotional when responding the notion that this is a tactic by Republicans to be obstructionists.
