In Denver last month, the Denver Classroom Teachers Association held a training with 200 members to educate teachers about the role that toxic swaps had played in draining hundreds of millions out of the district budget. Denver Public Schools was trapped in some of the most egregious predatory financial deals in the country and had to pay huge termination penalties to get out. One of the former school board members who voted to approve the deals in 2008 has now come forth as a whistleblower, demanding that the SEC investigate the deals.
