This is a strange proof of truth. I have never found Congress to be particularly interested in "truth" or even fairness for that matter.
Convincing 535 politicians is not the burden on those of us who are convinced something fishy occurred. Convincing the public is... Congress, as usual, will follow.
Most of the public walked away years ago after too many unfulfilled promises of "shocking new facts about Flight 800" from the conspiracy theorists.
Most of the conspiracy theorists themselves have lost interest as evidenced by the handful posting here, in the Yahoo Flight 800 Forum and the Donaldson TWA800 forum (which had only two postings during the entire month of August 2002).
