Democrats are digging in their heels following EPA’s proposal to roll back the scientific finding that underpins federal rules against planet-warming greenhouse gas emissions. Climate-minded Republicans, on the other hand, appear to be giving President Donald Trump the benefit of the doubt. The administration moved Tuesday to overturn a 16-year-old endangerment finding, which says greenhouse gas emissions pose a threat to human health. Congressional Democrats promised Tuesday to fight EPA’s actions by encouraging legal challenges and expanded state climate efforts.
