Illinois Treasurer Mike Frerichs says the state budget impasse could affect "critically important" services run through by his office.
The Springfield bureau of Lee Enterprises newspapers reports the Democrat from Champaign wrote a letter to top state leaders this week saying banking and financial services may stop if he can't pay vendors.
He says his office also might not be able to make funds available to Illinois Comptroller Leslie Munger. That means less money for available to pay state workers and pay vendors.
Republican Gov. Bruce Rauner and legislative Democrats can't agree on a July 1 fiscal year budget.
Other constitutional officers have weighed in on the impact. Secretary of State Jesse White says his office can't pay its bills and will stop sending out some public reminders.
