Lax state and federal laws allow this to happen.
Craig Mauger of the Detroit News reports:
Allies of Michigan Gov. Gretchen Whitmer used millions of dollars from secret donors and a web of nonprofit organizations to promote her policy agenda and celebrate Democrats who joined in championing it, according to a tax filing obtained by The Detroit News.
Since 2020, supporters of Whitmer, a Democrat, have raised about $30 million through a Lansing-based nonprofit called Road to Michigan's Future. The group's annual tax filing for 2023 was due to the Internal Revenue Service on Friday, and it showed $4.89 million in new contributions from backers who, under state and federal laws, didn't have to be publicly identified. Eight individual donors gave at least $200,000 each, including two that gave $500,000 each, according to the tax document.
