A conservative group in Michigan has filed a campaign finance complaint against Gov. Gretchen Whitmer, alleging she received illegal contributions during her recent record-breaking fundraising haul.

The Michigan Freedom Fund, which “fights to champion conservative policies on behalf of Michigan taxpayers,” filed a complaint Wednesday with Michigan’s Bureau of Elections outlining Whitmer’s “illegal scheme … to evade and eviscerate Michigan candidate contribution limits,” arguing contributions from at least 154 individual donors to Whitmer’s campaign violate state election laws.
