On May 2, 2016, Mt. Clemens political activist Greg Murray filed ethics complaints with the Macomb County Ethics Board against Miller and Sabaugh, saying the pair colluded with former Michigan Democratic Party Chairman Mark Brewer, who filed to run for Miller's seat on the Macomb County Board of Commissioners, saying that Miller personally filed Brewer's paperwork just minutes before the April 19th 4 p.m. filing deadline, an accusation that Miller refused to deny directly. County Executive Mark Hackel said the accusations were "extremely questionable” and that the situation "...doesn’t come across well for voters."
