Michigan Gov. Rick Synder said Tuesday retirees in Detroit made a tough decision for the motor city's future.

"This vote is recognition that all of Michigan has pulled together to support our state’s largest, and iconic, city and the people who work to protect and provide services to its residents," he said in a statement.

Results released shortly before midnight show overwhelming support for the plan to help Detroit with its bankruptcy. Detroit planners are working to eliminate or cut $18 billion in long-term debt.

Retirees agreed to a 4.5 percent cut in pensions and forfeit inflation adjustments. Retired police officers and firefighter lose only their cost-of-living adjustments. More than 70 percent of both groups voted in favor of the changes.

"These were difficult decisions for many people," Snyder said.
