More than one million Houstonians could have new congressional representation as early as next year under Gov. Greg Abbott’s push to redraw the state’s political maps.

Abbott has ordered the Texas Legislature into a special session beginning July 21 that includes redrawing the state’s congressional districts. In his order Wednesday, the Republican governor singled out Houston’s majority-minority areas like the Greater Fifth Ward and the East End, suggesting their boundaries could be reshuffled ahead of the midterm elections.

President Donald Trump’s political team has been pressing lawmakers to redraw Texas’ congressional districts to help Republicans pick up additional seats next November as they look to defend their U.S. House majority against a potential Democratic surge.
