MINNEAPOLIS — Make-A-Wish Minnesota has cut ties with a vehicle-donation charity that’s being investigated by the state’s attorney general, the chairman of the organization’s state board said Tuesday.

In an emailed response to a question from The Associated Press, Make-A-Wish Minnesota board chairman Mike Kust said: “I am confirming that we have ended our relationship with the Car Donation Foundation. We have no additional details at this time.”

Car Donation Foundation was accused last week of putting a fraction of money toward its advertised mission while steering millions to for-profit companies owned by the group’s founders. Attorney General Lori Swanson said her investigators found that during a four-year period, about one-fifth of Car Donation Foundation’s $108 million in gross revenue went toward charitable grants.

The St. Paul-based foundation solicits vehicle donations under a “Wheels for Wishes” program that pledges the proceeds to local Make-A-Wish chapters to help children battling cancer. It uses Make-A-Wish logos on its website.

Swanson accused the Car Donation Foundation of lacking transparency.
