From the article: According to documents whistleblower Edward Snowden leaked to the Washington Post, the U.S. spent $500 billion on its intelligence agencies in the dozen years after the 9/11 attacks, including annual appropriations in 2012 of $11 billion for the National Security Agency (NSA) and $15 billion for the CIA. If we add the $790 billion expended on the Department of Homeland Security to that $500 billion for overseas intelligence, then Washington had spent nearly $1.3 trillion to build a secret state-within-the-state of absolutely unprecedented size and power.
