California Democrats are rushing to schedule an election to remake U.S. House districts to counter plans to boost Republican seats in Texas

As a Texas senator summoned the F.B.I. to round up Democrats, the redistricting war that began in Texas was spreading, with California aiming at five Republican House seats.

If Texas Republicans go through with their plan to redraw the state's congressional districts to give Republicans five more U.S. House seats, California Gov. Gavin Newsom, a Democrat, says he'll push through new districts in his state that benefit Democrats.
