Illinois Gov. JB Pritzker (D) said Sunday it would be illegal for President Trump to order the FBI to arrest Texas state Democratic officials for fleeing their state to halt Republican redistricting efforts.

Texas Democrats are facing a full-blown retaliation campaign after fleeing the state to block a Trump-backed redistricting plan including lawsuits, potential arrests, and even calls for the FBI to track them down.

Will the FBI help the Republican Party force through a partisan redistricting plan in Texas, or not? The answer to that question is of vital importance to sustaining American democracy. Republican state legislative leaders want to redraw Texas’s congressional districts to give their party as many as five more seats in next year’s midterm elections.
