A state senator says the Michigan Economic Development Corporation gives out too many tax credits to businesses without enough oversight. State Senator Nancy Cassis says the MEDC gave out a year's worth of tax credits in six months. Cassis says she wants more details on how successful the businesses that get the tax credits are at creating jobs. The president of the MEDC says he agrees there should be more transparency in handing out tax credits. But he says the state can't be so intrusive that it drives away companies that might want to locate in Michigan and hire workers.
