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.

Both Texas Republicans and Democrats are ratcheting up their rhetoric over proposed US House maps that could give the GOP five more seats. But the action in Austin is stalled for now.
