Legislation that sets in motion the closure of Minnesota's second largest prison over the next four years is on its way to Gov. Tim Walz's desk for signature.

Labor unions representing correctional officers and staff in the Department of Correction are holding a press conference Friday, asking state leaders, both Republican and Democrat, and Gov. Tim Walz to stop the closure of Minnesota Correctional Facility–Stillwater (MCF–Stillwater).

If the plan is approved by lawmakers, the closure would phase in over four years with final closure set for June 30, 2029.
