Hemisphere isn’t a “partnership” but rather a product AT&T developed, marketed, and sold at a cost of millions of dollars per year to taxpayers. No warrant is required to make use of the company’s massive trove of data, according to AT&T documents, only a promise from law enforcement to not disclose Hemisphere if an investigation using it becomes public.
Lobbying data: AT&T contributions to Russ Feingold, Jim Doyle, Tammy Baldwin, Scott Walker and Ron Johnson.
