"White House Threatens Veto of Move to Thwart E.P.A."
"The White House made clear on Tuesday what had been assumed for months – that it does not like a resolution sponsored by Senator Lisa Murkowski, Republican of Alaska, that would thwart the Environmental Protection Agency’s ability to regulate greenhouse gases.
The White House says that if the resolution, scheduled for debate and a vote on Thursday, reaches President Obama’s desk, his advisers will recommend that he veto it. That’s what is known as a veto threat and in this case it is not a bluff."
