Byrd, Rockefeller wary of global warming bill 

CHARLESTON, W.Va. -- One of West Virginia's U.S. senators is opposed to the landmark global warming bill that passed the House Friday, while the other has "serious concerns" about the measure.

Aides to Sen. Robert C. Byrd issued a statement Monday that said Byrd "cannot support" the American Clean Energy and Security Act "in its present form."

Sen. Jay Rockefeller's office also issued a statement that said Rockefeller "continues to have serious concerns about the House bill."

Byrd and Rockefeller are both Democrats, and their party needs 60 votes in the Senate to block a potential Republican filibuster once the legislation reaches the floor. Currently, Democrats hold 59 of the Senate's 100 seats.
