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.

Under the newly drawn maps, Republicans will likely increase the number of seats in Texas from 25 to 30, and Democrats will see their number of seats drop from 13 to eight. Lawmakers from both parties blamed each other for using race.

Just as Democratic U.S. Senate candidate Colin Allred was holding a town hall near the Mexican border as part of an “unrig Texas” campaign tour, the state’s Democratic fundraising powerhouse Beto O’Rourke rallied support in Austin for lawmakers who left the state to delay a redistricting plan led by President Donald Trump.
