Mayor Brandon Johnson exercised his veto power on October 9, 2026, rejecting an ordinance that would have required the support of at least 30 alderpeople and a three‑fifths vote of the Chicago City Council to authorize any new city borrowing.
The council had approved the measure on September 30, 2026, passing it by a 32‑15 vote. The proposed rule was intended to make it more difficult for the city to take on additional debt.
