RED LINE: Roll Call: White House Threatened Veto of Spending Bill Over McConnell Amendment.

Top senators signaled the White House threatened to veto a Senate spending bill over a possible amendment from Minority Leader Mitch McConnell to block EPA power plant regulations.

The amendment, billed by the Kentucky Republican as a fight against the Environmental Protection Agency’s “war on coal” was cited by the chairwomen of the full Appropriations Committee and the Energy-Water Subcommittee as the key factor in removing that fiscal 2015 bill from Thursday morning’s markup agenda.. . .

McConnell’s amendment would have required certification of no job losses or electricity cost increases as a result of the implementation of the EPA’s proposed regulations on carbon emissions from existing power plants. . . .

Energy-Water ranking member Lamar Alexander, R-Tenn., tied the delay of the bill that he worked to craft with Feinstein to the broader GOP complaints about the floor operations of Senate Majority Leader Harry Reid, D-Nev., including a recurring blockade of floor amendments.

Reid’s running the Senate — into the ground.
