SPRINGFIELD, Ill. (AP) — The Illinois State Museum system is in danger of losing its national accreditation after Gov. Bruce Rauner closed the museums due to the state budget impasse.

The American Alliance of Museums’ Accreditation Commission voted 7-0 on Monday to put the museum system on probation.

Accreditation Commission Chairman Burt Logan says there are “grave concerns” about the impact of the closure on the museum’s long-term viability. The Illinois State Museum system has had accreditation from the Arlington, Virginia-based alliance since 1972. The group recognizes museums that meet certain criteria for collections, staff, financial stability and other areas.

The Republican governor said he closed the Springfield museum and four satellite sites as part of his efforts to manage state finances while he and the Democrat-led Legislature are deadlocked over a state budget.
