In a wide-ranging interview with NBC News, the California governor slammed the GOP-controlled Congress and the Supreme Court for bowing to Trump.

California Gov. Gavin Newsom on Thursday said he’s “deeply confident” that California voters this week will approve the state’s Prop 50 ballot measure, which would allow the state to redraw congressional maps on a partisan basis ahead of next year’s midterm elections.

In a wide-ranging interview, the California governor slammed the president’s push for mid-decade redistricting efforts in Republican states across the country, accusing the president of “rigging” next year’s congressional election and warning that Trump “is not screwing around.”

“He’s changing the rules. He’s rigging the game because he knows he’ll lose if all things are equal,” Newsom told Welker. “He did not expect California to fight fire with fire.”
