A California legislative hearing turned into a shouting match Tuesday as a Republican lawmaker clashed with Democrats over a partisan plan to rewrite U.S. House maps to win Democrats more seats.

Texas Democrats end walkout as GOP-controlled legislature prepares to vote on redistricting maps that could flip five congressional seats to Republicans

Proposed new congressional maps in California could help Democrats flip five Republican seats and bolster around five Democratic incumbents in toss-up districts.

Rep. George Whitesides, a prime GOP target, would be in a bluer district as other Dems pick up more Republican voters.

One of the pieces of legislation involved in the process, AB 604, states that the detailed maps have been prepared by the Assembly Committee on Elections and the Senate Committee on Elections. But neither leader of the committees would confirm Tuesday that those committees are drawing the maps.

The new, partisan maps come on the heels of Gov. Gavin Newsom’s launch of California’s redistricting campaign on Thursday, an effort he touted as meant to favor Democrats in California in the upcoming midterm elections as a counter to similar efforts in Republican-led states elsewhere in the country.
