Detroit Emergency Manager Kevyn Orr, after reportedly making progress Tuesday and Wednesday, plans to return to Lansing next week to push for state money to aid the city’s bankruptcy settlement, but he’ll do so as anti-tax activists say they will pull out all the stops to squash the move, the Detroit Free Press reported today. The leader of a Michigan anti-tax group affiliated with the Tea Party movement, Americans for Prosperity, said that his group will fight any such appropriation and plans to mail literature and make phone calls to certain lawmakers’ home districts to put the pressure on. Orr is expected to caucus with Republicans next week as they prepare to introduce a package of bills to provide for the state contribution. The proposal is the equivalent of $350 million over 20 years, but there is growing traction in Lansing for a single up-front payment that would be closer to $200 million.
