Morrisey has become one of the leading Attorneys General in the fight against President Obama's overreaching, illegal EPA regulations. In February 2016, under Morrisey's leadership, the Supreme Court halted implementation of Obama's signature climate change initiative, the Clean Power Plan, in an unprecedented win for AG Morrisey and the 28 other state Attorneys General.
In 2015, Morrisey helped lead a coalition of states to challenge and win a stay against the EPA "Waters of the United States" rule, a significant victory for homeowners, farmers, and businesses across the country. His legal victories against the Obama Administration have helped to protect West Virginia jobs and uphold the rule of law.
