We've spent all week glued to the House Energy & Commerce Committee video feed, taking notes for you on the committee's hearings on the American Clean Energy and Security Act of 2009. That's the draft clean energy & climate legislation introduced by Rep. Henry Waxman (D-CA) and Rep. Edward Markey (D-MA).

But today is the main event. Set to testify are former Sen. John Warner (R-VA), former Vice President Al Gore and former House Speaker Newt Gingrich. The question is, which Newt will show up? "Look at Me, I'm Centrist and Presidential" Newt who cut an ad for Gore's We Campaign declaring "our country must take action to address climate change"? Or "My 527 Needs Big Oil Money" Newt, who used voodoo economics to trash President Obama's clean energy & climate action plan?

The hearings are due to start at 10am and we'll have minute-by-minute notes over at DailyKos!
