COLUMBIA, S.C. AP – South Carolina’s top prosecutor said Tuesday that he’s pleased with oral arguments before the nation’s highest court as to why a city, a water supply company and a major utility should stay out of a water dispute with North Carolina.

“I was very happy to see the intense interest that they are taking in the case,” South Carolina Attorney General Henry McMaster said by phone from Washington after the hour-long hearing before the U.S. Supreme Court. “I have never seen the justices appear to be as interested and knowledgeable and active in their questions. They were highly engaged.”
