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.

Gavin Newsom unveiled plans on Thursday to alter the state’s boundaries to try to flip at least five seats into Democratic control next November — negating the five Republican seats Texas lawmakers hope to gain with their new maps currently under consideration.
