Texas and California — the two most populous U.S. states — are the leading actors in a back-and-forth push to remake the balance of power in the U.S. House, kicked off when President Donald Trump called for Texas to redraw district lines with the GOP’s fragile House majority imperiled in the upcoming 2026 midterm elections.

Texas has been the epicenter of Trump’s push to gerrymander congressional maps to shore up Republicans’ narrow House majority before next year. But the standoff is threatening to into other states — including California.

Texas Attorney General Ken Paxton filed a lawsuit directly to the all-Republican state Supreme Court on Friday seeking to have 13 of the Democratic lawmakers immediately removed from office, or at least given a 48-hour warning that they must return or have their offices declared vacated.
