It’s unlikely that United Mine Workers of America president Cecil Roberts thought he would be arrested protesting the energy policies of the very politician his union supported in 2008. But things have come full circle for coal miners, who now see President Obama’s climate agenda threatening their livelihoods.

Roberts and other UMWA members were arrested Thursday marching through Pittsburgh, Pennsylvania, towards the federal building the Environmental Protection Agency was holding field hearings for a new rule that could very well force more coal mines and plants to shut down.

Roberts was leading about 5,000 coal miners, their families and supporters to show the EPA that coal miners, boilermakers, electric workers and other unions did not support the Obama administration’s new regulations limiting carbon dioxide emissions from coal-fired power plants.
