Paxton wrote in an opinion that clerks can deny those licenses but should be prepared to face lawsuits over that.

The U.S. Supreme Court ruled 5-4 in favor of a coalition of states including Texas, which sued the Environmental Protection Agency over its regulations on mercury, acid gases and other toxic metals emissions that spew from power plants.

The U.S. Supreme Court sided with Texas abortion providers and temporarily put on hold a ruling that would have closed about half of the state’s abortion facilities.
