After a long day of debate, the Texas House of Representatives passed Republican-favored congressional maps Wednesday evening that could flip five districts red by merging Democratic seats in the Houston, Austin, and Dallas-Fort Worth areas to form new Republican-leaning seats and by making two Rio Grande Valley districts currently held by Democrats more competitive.

Districts currently held by Democratic Reps. Al Green, Marc Veasey, Julie Johnson, Greg Casar and Lloyd Doggett are potentially targeted.

The vote came weeks after state Democrats decried the unorthodox mid-decade redistricting as blatant gerrymandering to increase the number of GOP congressional seats.

The special session was delayed after Democrats left the state to avoid a quorum, despite threats of arrest from Gov. Greg Abbott and other Republican leaders.

Some Democrats returned to the statehouse on Monday and allowed the legislature to reach a quorum, but they continued to speak out against the controversial redistricting.

It is likely that the redistricting plan, which was pushed by President Donald Trump, will pass. The map could pass the state Senate as soon as the end of the week and would then go to Gov. Greg Abbott for his signature.

A handful of Texas House Democrats refused law enforcement escorts to ensure they wouldn’t leave the state again. They stayed overnight in the Texas House in solidarity with state Rep. Nicole Collier, who had refused to sign a “permission slip” allowing her to leave the state Capitol with a law enforcement escort.

The Texas state Capitol also dealt with a social media threat Tuesday night that led to the evacuation of grounds and the building, but Democratic lawmakers who were already in the building remained inside.

The bill, which was newly filed for the second special session after the first one was adjourned due to not having a quorum, passed out of committee on Monday.
