California's governor said on Friday he will ask voters to approve a ballot measure in November redrawing the state's congressional map in a way likely to create five more Democratic seats, escalating a redistricting war with the Republican-led state of Texas and President Donald Trump.

Democrats have left the state, the Republican governor and attorney general have vowed to remove them from office, and a senator has called in the F.B.I.

Texas Republicans are planning to escalate their efforts to end a weeklong holdout by Democrats if they don’t return to the state Capitol to face a vote on new congressional voting maps
