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.

California Gov. Newsom moves forward with putting proposed congressional maps on the ballot in Nov. 4 special election in attempt to counter GOP redistricting in Texas.
