Like many of my colleagues, I believe this legislation needs to be debated, amended, improved, and ultimately, enacted. While my schedule precludes me from being in Washington, DC, tomorrow to cast my vote, if I were able, I would vote to invoke cloture on the substitute amendment. That does not mean I believe the pending bill is perfect, and in fact, it is far from it. For example, the provisions to impose Davis Bacon mandates should be removed. Most importantly, it must include provisions championed by Senator Graham and myself that would ensure that nuclear power, a proven and clean energy source, is included among the technologies supported in our efforts to address global warming. Nuclear energy is an emission free source of electricity for the nation, which is why it simply must be part of the comprehensive solution to addressing climate change, and if it is not, I could not support the legislation's final passage.
