Former President Barack Obama has waded into states’ efforts at rare mid-decade redistricting efforts, saying he agrees with California Gov. Gavin Newsom’s response to alter his state’s congressional maps, in the way of Texas redistricting efforts promoted by President Donald Trump aimed at shoring up Republicans’ position in next year’s elections.

The Republican-controlled state House in Texas has passed new congressional maps that aim to pad the party’s majority in Washington by as much as five seats in the midterm elections, a move that comes as battles over redistricting spread across the country.

California races toward redrawing congressional maps as Texas moves toward final approval of its plans. California Democrats are rushing Thursday to advance a plan to draw a new congressional map, aiming to counter Texas Republicans in a national fight between the two parties to seize an advantage in next year’s midterm elections.
