California Gov. Gavin Newsom, a committed thorn in Donald Trump’s side, told the president Monday that he’s prepared to redraw California’s districts in Democrats’ favor if he doesn’t call on Texas and other red states to halt their own GOP-friendly redistricting plans.

Gov. Gavin Newsom and Texas Democrats jointly promoted California’s plan to redraw congressional lines and offset a redistricting scheme in Texas.

Texas Democratic lawmakers remain outside of the state in an attempt to deny their GOP colleagues the quorum to vote on an aggressive redistricting play.
