The Trump administration has asked the Supreme Court to take up a water fight between Nebraska and Colorado.

In a filing with the high court Wednesday, Solicitor General D. John Sauer argued that the states’ brawl over the South Platte River is precisely the type of interstate dispute that should get “distinct disposition” by the justices.

“A claim that one State has deprived another of water to which it is entitled under an interstate compact is a quintessential case for this Court’s original jurisdiction,” Sauer wrote. “And because Nebraska’s challenge is purely factual, that claim is best addressed by a special master in the first instance.”
