The Texas senate has given final approval to a redrawn congressional map that gives Republicans a chance to pick up as many as five congressional seats, fulfilling a brazen political request from Donald Trump to shore up the GOP’s standing before next year’s midterm elections.

It will now be sent to governor Greg Abbott, a Republican, who is expected to quickly sign it into law, however Democrats have vowed to challenge it in court. The Texas house of representatives approved the map on Wednesday on an 88-52 party-line vote, before the senate approved it early on Saturday.

Democrats had prepared for a final show of resistance, with plans to push the senate vote into the early morning hours in a last-ditch attempt to delay passage. But the planned filibuster was thwarted by a procedural motion by Republicans. It now heads to the governor for final approval.
