Republicans can move ahead with redrawing Texas’ congressional districts now that Democratic lawmakers have returned to the state.

Texas House Democrats who fled their state to stall a Republican redistricting effort returned on Monday, ending their 15-day holdout. While Democrats have vowed to keep fighting, their return allows the House to establish a two-thirds quorum necessary to advance new congressional maps in a push backed by President Donald Trump.

Democratic leaders say they will return for a second special legislative session after seeing California Democratic leaders proceed with plans to redraw their own U.S. House maps to neutralize Republican gains in Texas.
