Frustrated by President Trump's decision to withdraw the U.S. from the Paris climate agreement, several governors have joined together to create the United States Climate Alliance.
The alliance is the brainchild of Washington Gov. Jay Inslee, New York Gov. Andrew Cuomo and California Gov. Jerry Brown, the first three states to join last week. All three are Democrats.
Nine more states — Connecticut, Delaware, Hawaii, Massachusetts, Minnesota, Oregon, Rhode Island, Vermont and Virginia — joined the coalition this week. Puerto Rico has also enrolled. The only states with a Republican governor to join so far are Massachusetts and Vermont.
