President Donald Trump ignited the conflict over redistricting last year by urging Republicans to redraw congressional maps to reduce the likelihood that his party loses the U.S. House in the November midterm elections.

Republicans and Democrats are in an escalating national fight over congressional seats. Some members of Congress are pushing for Illinois to redraw its districts to get another Democratic seat.

In Illinois, there are numerous security checks in place to ensure the accuracy and security of mail-in voting, according to Matt Dietrich, a spokesperson for the state’s Board of Elections.
