Vote harvesting is illegal in Michigan.
But per WDIV:
Video obtained by Local 4 shows what appears to be a current Hamtramck councilmember dropping off stacks of absentee ballots at a city drop box days before the August primary election. […]
The passenger, identified by sources as current City Council Member Abu Musa, hands several large bundles of what appear to be absentee ballots to the driver, who then deposits them into the box.
This development comes as Musa, who received more than 1,129 votes in last week’s primary election, seeks reelection to the council.
