The legal bills continue piling up in former Republican operative Michael Brodkorb’s lawsuit against the Minnesota Senate. The state Rules Committee met Wednesday afternoon to consider the latest invoice — nearly $28,000 — from the law firm representing the state Senate, with the tab paid so far totaling over $226,000. The committee agreed to set aside $500,000 in state money to be used towards the lawsuit. Brodkorb was fired after having an affair in 2011 with then Senate Republican Majority Leader Amy Koch, who stepped down from the leadership position after colleagues confronted her about the affair. Brodkorb says he was treated differently than female staffers whom he alleges have had inappropriate relationships with male lawmakers. The lawsuit is scheduled for trial next summer.
