Senate overturns EPA on California waiver

A Senate panel has narrowly voted to overturn the EPA's decision to block California and more than a dozen other states from limiting greenhouse gas emissions from vehicles.

The bill by Democratic Sen. Barbara Boxer of California passed the Environment and Public Works committee by a 10-9 vote Wednesday, sending it to the full Senate.

One committee Democrat, Sen. Tom Carper of Delaware, broke with others on his side of the aisle and voted no. Republican John Warner of Virginia voted yes, allowing the bill to pass.
