Texas House Democrats are planning to leave the state in an effort to block a vote on proposed congressional maps during a special legislative session. The Democrats' move is intended to break quorum, preventing the Republican-controlled House from passing a redistricting plan that could give the GOP an additional five seats in Congress. This action is a significant escalation in the ongoing battle over redistricting in Texas, with Democrats arguing that the proposed maps unfairly favor Republicans and disenfranchise minority voters.
