O'Fallon councilmember Nathan Bibb resigns, saying ownership change created conflict

Councilmember Nathan Bibb announced his immediate resignation from the O'Fallon City Council at the Sept. 11 meeting, saying a unilateral change to a 'castle' project — shifting the project owner from the Castle board to the city — created a conflict he did not have when the contract was awarded.

"This unilateral change now creates a conflict for me that I did not have existing previously," Bibb said, and added that while he could pursue litigation, it would be "a loss for everyone involved." He said he had served the community for more than six years and was stepping down "under duress."

Fellow council members responded with appreciation and reflection. Councilmember Keelan praised Bibb's decision to step down, saying, "I applaud Mister Bibb for stepping down, for falling on his sword," while also defending the original procurement process as lawful and consistent with the city charter. Several members used their remarks to urge civility in public discourse, tying the comments to recent national incidents and to the Sept. 11 remembrance.

Mayor Hennessy and city staff offered thanks for Bibb's service. The mayor called for continuity in council work and indicated staff would proceed with agenda items scheduled for the evening.

The resignation came during Ward 3 remarks and was immediately acknowledged in roll call and later in mayoral remarks. The council did not take a follow-up vote on filling the vacancy at that meeting; no successor was named on Sept. 11.
