FILE - This Feb. 4, 2014 file photo shows Senate Minority Leader Mitch McConnell of Ky. during a news conference on Capitol Hill in Washington. The Supreme Court appeared divided on Monday over the sole Obama administration program already in place to limit power plant and factory emissions of gases blamed for global warming. The presence of McConnell in the courtroom underscored the political stakes in President Barack Obama’s high-profile effort to deal with global warming _ a policy Obama is pursuing after failing to persuade Congress to enact climate change legislation. McConnell is facing a tough re-election fight in which he refers often to the administration’s assault on the coal industry in Kentucky and elsewhere. (AP Photo/J. Scott Applewhite, File)
