More than 50 Texas House Democrats left the state Sunday, one day after a bill that would dramatically redraw Texas’ congressional maps passed a state legislative committee in the GOP-led House of Representatives.
The Texas House requires 100 members be present to conduct business, and the House only includes 88 Republicans. The Democrats’ action, known as “breaking quorum,” effectively brings the House to a standstill and prevents any consideration of the bill by the full chamber.

The heavily redrawn congressional maps, which are backed by President Trump, could give Republicans five extra seats in the midterm elections. House Democratic Caucus Chair Gene Wu spoke in a Chicago suburb, flanked by fellow House Democrats and Illinois Governor JB Pritzker.

“If Donald Trump is allowed to do this, if he is allowed to, once again, cheat and get away with it, there is no stopping this. This will spread across the country.”

Texas Gov. Greg Abbott said that if those Democrats who have broken quorum do not return to the Capitol immediately, he will invoke a ruling by state Attorney General Ken Paxton to have them expelled from the Texas House.
