It’s well-known that Sidney Harman, the electronics mogul who just bought Newsweek, is married to Rep. Jane Harman, one of Washington’s heavyweights on intelligence.

Rep. Harman, a Democrat, spent eight years on the House Intelligence Committee and is chairwoman of the Homeland Security Subcommittee on Intelligence & Terrorism. She has had an intimate, and sometimes controversial, relationship to America’s spy agencies during her eight terms in Congress.

But few in Washington are aware that the real intelligence insider of the Harman family may be Sidney himself, through his connections to an obscure but highly influential organization known as Business Executives for National Security.
