CPI:

Americans for Prosperity — the main political arm of billionaire industrialist brothers Charles and David Koch — spent a staggering $122 million last year as it unsuccessfully attempted to defeat President Barack Obama and congressional Democrats, according to a Center for Public Integrity review of documents filed in Colorado.

That’s more than the total amount the group had previously spent from its formation in 2004 through 2011. During its previous eight years of existence, Americans for Prosperity spent a combined $72 million, a review of Internal Revenue Service records indicates.
