Seventy percent of the intelligence community’s budget goes to paying contracts. And the membrane between government and industry is highly permeable: The Director of National Intelligence, James R. Clapper, is a former executive of Booz Allen Hamilton, one of the government’s largest intelligence contractors. His predecessor as director, Admiral Mike McConnell, is the current vice chairman of the same company; Booz Allen is 99 percent dependent on government business.

These contractors now set the political and social tone of Washington, just as they are increasingly setting the direction of the country, but they are doing it quietly, their doings unrecorded in the Congressional Record or the Federal Register, and are rarely subject to congressional hearings.
