Over 50 Democratic lawmakers from Texas left the state on Sunday to ensure that the state legislature doesn’t have a quorum to pass a redistricting vote being pushed by the GOP.

Texas House Democrats left the state Sunday in a desperate bid to block an aggressively partisan redrawing of the state’s congressional map orchestrated by Republicans with the support of President Donald Trump.

The lawmakers’ absence means the lower chamber won’t have enough members present to function, stalling passage of a draft map Democrats have condemned as a political power grab.
