Republicans say they'll go to federal court this week to try to block new court-ordered boundaries of Pennsylvania's congressional districts from remaining in effect for 2018's elections.
Top Senate Republican lawyer Drew Crompton said Monday a separation of powers case will form the essence of the GOP's argument. Crompton won't say whether Republicans will go to a district court or the U.S. Supreme Court or what type of legal remedy they'll seek.
But the case will involve making the argument the U.S. Constitution gives state legislatures and governors, not courts, the power to draw congressional boundaries.
Earlier this month, the U.S. Supreme Court wouldn't stop the state court's order to redraw congressional districts.
Democratic Gov. Tom Wolf calls the new map an effort to remedy the state's unfair and unequal congressional elections.
