Springfield attorney and former chair of the Illinois Republican Party Don Tracy announced Wednesday he is running for U.S. Senate — adding to a field of candidates making a bid for outgoing Sen. Dick Durbin’s seat.

Illinois Senator Dick Durbin joined Texas Democrats to warn that the redistricting fight in the Lone Star State is the first sign of a threat to the whole country.

Durbin was originally supposed to speak alongside the lawmakers last week, before a bomb threat was reported at the hotel some of the Texas representatives were staying at.
