A walkout by Democratic legislators in Texas has ended, and Republicans are arranging to push a plan for redrawing the state’s congressional districts through the GOP-controlled Legislature.

State Rep. Todd Hunter, a Corpus Christi Republican, introduced the new map and was open about how the changes are meant to “increase Republican performance.”

The proposed congressional districts are fueling a redistricting battle at the Texas Capitol and could have national consequences. A bipartisan war is already brewing across the U.S.

Democratic leaders say they will return for a second special legislative session after seeing California Democratic leaders proceed with plans to redraw their own U.S. House maps to neutralize Republican gains in Texas.

A crowd of supporters cheered the Democratic lawmakers’ return, but Republicans are ready to approve the new congressional map called for by President Trump that Democrats tried to block.
