Do the committees that oversee the vast U.S. spying apparatus take intelligence community whistleblowers seriously? Do they earnestly investigate reports of waste, fraud, abuse, professional negligence, or crimes against the Constitution reported by employees or contractors working for agencies like the CIA or NSA? For the last 20 years, the answer has been a resounding "no."

My own experience in 1995-96 is illustrative. Over a two-year period working with my wife, Robin (who was a CIA detailee to a Senate committee at the time), we discovered that, contrary to the public statements by then-Chairman of the Joint Chiefs Colin Powell and other senior George H. W. Bush administration officials (including CIA Director John Deutch), American troops had in fact been exposed to chemical agents during and after the 1991 war with Saddam Hussein. While the Senate Banking Committee under then-Chairman Don Riegle, D-Mich., was trying to uncover the truth of this, officials at the Pentagon and CIA were working to bury it.

At the CIA, I objected internally — and was immediately placed under investigation by the CIA's Office of Security.
