Texas Gov. Greg Abbott has promised to sign a new congressional voting map designed to help Republicans maintain their slim majority in Congress.

The Texas Senate on Saturday approved new congressional maps drawn to help Republicans win as many as five more House seats in next year’s midterm elections.

The Texas Senate passed a bill creating new congressional districts designed to eliminate five districts held by Democrats, sending the bill to Gov. Greg Abbott’s desk to end a weeks-long battle that has since sparked retaliation as California Gov. Gavin Newsom leads an effort to redraw his state’s districts in response.
