What I did find is that Mike Griffin, the aerospace engineer who became the top NASA administrator in 2005, had a previous job as president of In-Q-Tel, the CIA’s in-house venture-capital fund for national security tech.
He invested $500 million in commercial space, eventually $396 million eventually going to SpaceX, along with $454 million of outside capital and $100 million of Musk's own money in 2006. [0]
So, if there is in In-Q-Tel investment, it is logged behind the Crunchbase paywall. That said, In-Q-Tel is an excellent idea to produce better home-grown security technology, and I have no problem with it (not even with their publicized investment in Facebook, and I consider FB a plague on humanity — that's more of a slur on In-Q-Tel than In-Q-Tel is on FB).
