Four California Republicans have filed a lawsuit seeking to block Governor Gavin Newsom's redistricting plan, which would create five new Democratic U.S. congressional seats in his state to counter a similar move by Republicans in Texas.

California lawmakers returned to the state Capitol on Monday to begin their march toward passing Gov. Gavin Newsom’s (D) redistricting plan, vowing to “fight back” and even the scales ahead of the midterm elections.

The bill is scheduled to hit the California legislature's election committee on Tuesday, then the appropriations committee Wednesday. If it passes those committees, a full vote by both houses will need to happen by Thursday to meet California's secretary of state deadline to get the initiative on a Nov. 4 special election ballot.
