Opening a new front in the assault on teacher tenure, a group of parents backed by wealthy philanthropists served notice to defendants on Wednesday in a lawsuit challenging Minnesota’s job protections for teachers, as well as the state’s rules governing which teachers are laid off as a result of budget cuts...
...The Minnesota lawsuit names the state, Gov. Mark Dayton, the state Education Department and its commissioner as defendants. The case is being supported by Partnership for Education Justice, a New York-based advocacy group that receives its primary funding from the foundations of the Walton family, the founders of Walmart, and the Los Angeles billionaire Eli Broad. Students for Education Reform, a group that also receives funding from the Broad and the Walton Family Foundations, is also backing the suit.

Note, Broad is the "B" in KB Homes. He founded the company, a company also gets a lot of money from the government in the form of roads around their massive housing developments.
