The Senate appears to be drifting away from the original climate change bill, authored by Sens. Barbara Boxer (D-Calif.), and John Kerry (D-Mass.) and moving toward a compromise measure designed to draw support from Republicans and moderate Democrats. Recently, Kerry, Sens. Lindsey Graham (R-S.C.) and Joe Lieberman (I-Conn.), held a news conference to announce they are working on a compromise that has earned a tentative endorsement from the U.S. Chamber of Commerce.  Kerry, Lieberman and Graham released few details about the new bill, but said it would include a cap-and-trade proposal. They said it would also address increasing nuclear energy, more drilling and clean coal technology.
