According to a report in Gongwer, Michigan Senate Republicans passed legislation last week that allows nonprofit organizations to not be forced to disclose their donors. Opponents of the bill called the measure a way of hiding who is contributing to political attack advertisements.

SB 1176 passed by a 25-12 vote. The bill prohibits public agencies from requiring any 501(c) designated organizations under the U.S. Internal Revenue Service to disclose donors without permission unless sought through a criminal warrant or through discovery in a lawsuit. This means that the Department of Attorney General or any agency conducting investigations would have to obtain a warrant to access such information about a charity group rather than merely requesting it.
