UPDATED: Anonymous Hits Chamber!
From source -
As we speak I'm sitting on a mile high pile of data released about the US Chamber of Commerce. Thousands and thousands of docs released a few hours ago. Wanna help read through the docs and see what crazy things the Chamber is up to? There's thousands of these docs. It's a 1.2 GIGABYTE download. My computer is choking on it. Looks like a lot of docs scraped from their sites.
...It contains documents from an organization that particularly makes my teeth curl, the Michigan based Mackinac Center for Public Policy. Those are the dudes who brought us the Overton Window. They're kind of nuts.
