Looks like Mandsager went ahead and filed his lawsuit this past Friday:
Mandsager accuses Broderson of five charges in the petition: defamation, infliction of emotional distress, intentional interference with prospective business advantage, intentional interference with contract and respondeat superior or municipality liability. He is requesting Broderson provide compensation for "injuries" and cost of legal action.He claims that he just wanted Mayor Broderson to issue him an apology and to retract claims that she has made about their initial meeting, where she's stated that he'd told her that he runs Muscatine and that he is the person that makes decisions. Meanwhile, Mayor Broderson claims that she's never been approached by Mandsager about the lawsuit or about his desire for an apology or for a retraction. (Which seems kind of disingenuous given that he's spoken about both the lawsuit and his desire for an apology recently in the news.)
Mandsager is seeking a trial by jury and unspecified monetary compensation.
Meanwhile, the Muscatine City Council unanimously voted to increase City Administrator's salary by 2% earlier today. His annual salary increased from $155,000 to $157,000.
Updated on 12/06/19: I totally fell behind on my Muscatine tracking over the past two years. Late last night, I discovered that the city of Muscatine ended up settling with City Administrator Gregg Mandsager for $50,000 and with Mayor Diana Broderson for $75,000. This all happened back in May 2019.
