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

The mid-decade map redraw adds five Republican-leaning districts and sets up a legal showdown over minority representation.

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.
