The Democratic lawmakers have been in Illinois since Aug. 3 to avoid a vote on the remap during a special legislative session called by Texas GOP.

The departure marked the end of a nationally-watched standoff between the lawmakers and Texas Gov. Greg Abbott, who pushed the remap plan at President Donald Trump’s urging in a bid to add five additional Republican seats in the U.

After two weeks out of state, Democratic lawmakers said they would return to Austin and lay the groundwork for a legal challenge to the GOP’s proposed congressional map.
