California voters will decide in a November special election whether to approve a redrawn congressional map designed to help Democrats win five more U.S. House seats next year.

The high-stakes fight over political boundaries could shape control of the U.S. House – and determine Gov. Gavin Newsom’s political future.

The Texas Senate could vote Friday to approve new congressional maps drawn to help Republicans win as many as five more House seats in next year’s midterm elections.

California Gov. Gavin Newsom on Thursday signed a series of bills calling for new congressional maps that could add up to five Democratic seats in Congress, a response to an ongoing, Trump-led effort in Texas to use redistricting there to carve out five additional GOP seats.

Democratic state Representative Nicole Collier spent the night in the Texas Capitol building rather than agree to a police monitor amid a contentious partisan struggle over redistricting that is part of President Donald Trump's campaign to keep the national House of Representatives in Republican hands.

Republicans hold a 219-212 majority in the House, with four vacancies. New maps are typically drawn once a decade after the census is conducted. Many states, including Texas, give legislators the power to draw maps. California is among states that rely on an independent commission that is supposed to be nonpartisan.
