ST. PAUL, Minn. (AP) - A Minnesota charity that relies on vehicle donations says it disagrees with a state attorney general report that too little of the money it raises goes to charity.

Car Donation Foundation said Wednesday the amounts it gives to charity meet or exceed industry standards. The foundation says car donation programs are expensive to run, and it's clear about costs on its website.

The foundation says it's given more than $1.5 million to Minnesota charities since 2011 and more than $30 million to charities nationwide since 2011.

Attorney General Lori Swanson said Wednesday that only about 20 percent of the foundation's gross revenue in the past four years has gone toward charitable grants. Swanson said the foundation had $37 million in revenue last year on almost 50,000 donated vehicles.
