The Koch Brothers’ Secret Bank

Freedom Partners, “whose existence until now was unknown to almost everyone in politics, raised and spent $250 million in 2012 to shape political and policy debate nationwide,” Politico reports.

The group serves “as an outlet for the ideas and funds of the mysterious Koch brothers, cutting checks as large as $63 million to groups promoting conservative causes, according to an IRS document to be filed shortly. The 38-page IRS filing amounts to the Rosetta Stone of the vast web of conservative groups — some prominent, some obscure — that spend time, money and resources to influence public debate, especially over Obamacare.”
