California Democrats are taking up their proposed constitutional amendment to temporarily redraw their congressional maps, hours after Republicans in the Texas House passed new maps of their own.

Republican lawmakers are pursuing the unusual mid-decade redistricting plan amid pressure from President Donald Trump to protect the GOP’s slim majority in the U.S. House.

The national redistricting battle enters its next phase Thursday as California Democrats are scheduled to pass a new congressional map that creates five winnable seats for their party, a direct counter to the Texas House's approval of a new map to create more conservative-leaning seats in that state.
