California Democrats introduced a plan last week that could slash five Republican-held House seats in the liberal-leaning state while bolstering Democratic incumbents in other battleground districts.

California's Democratic Legislature is expected to counter Texas' mid-decade redraw of its congressional map with one of its own.

Battles over redistricting in Texas and California are making national headlines, but only one state is required to redraw its maps this year: Ohio.

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. A committee voted along party lines to advance a new congressional map in response to a Republican redistricting effort in Texas that President Donald Trump wants.
