Rev. Al Sharpton and members of the National Action Network will be in Detroit on Thursday to announce they have joined a federal lawsuit challenging the state of Michigan's appointment of an emergency financial manger in Detroit.

Sharpton, who is president of NAN, will be joined by Detroit NAN President Rev. Charles Williams.

At 9 a.m. Thursday, the group will hold what it's calling a "leadership meeting" at 600 West Lafayette Boulevard. The meeting will be followed by the lawsuit filing at the federal courthouse at 231 West Lafayette Boulevard.
