As Texas House Democrats hunker down in Illinois to try to stop a Republican-led redistricting plan in their state, national Democrats and Gov. JB Pritzker ratcheted up their rhetoric.

Dozens of Texas Democrats have left the state in a bid to block a vote on redrawn U.S. House maps sought by Trump.

Democrats concede there’s only so much they can do to keep Texas from redrawing its maps. But they want to encourage blue states to retaliate.

Democrats who left the state have shown no signs of buckling for now: A group was scheduled to appear later Friday with California Gov. Gavin Newsom in a public show of support for the walkout.

Texas Republicans on Friday sought to increase the pressure on more than 50 Democratic lawmakers who left the state to prevent a vote on a new congressional map, announcing that absent state House members can only collect paychecks by appearing in person.
