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.

Texas Republicans will again try to convene the state Legislature Monday for a vote on redrawing congressional maps in their party’s favor, an effort that already sparked a national political brawl and prompted Democratic lawmakers to leave the state to deny Republicans the quorum they need.
