The Texas Senate approved a bill early on Saturday to redraw the state’s congressional maps at the behest of President Donald Trump in an effort to flip five seats held by Democrats to Republicans. The approval comes after the state House passed it on Wednesday, US media reported. The measure goes to Governor Greg Abbott, like Trump a Republican, to be signed into law amid a nationwide redistricting battle.

The effort is intended to help the G.O.P. win five more U.S. House seats in the midterm elections. Other states, red and blue, are likely to redraw their own maps.

Texas Republicans are near passing a new congressional map, sparking a response from California and igniting a new battle between Republicans and Democrats.
