Around May of 1983, approximately 4 months before being shot down in KAL007, Congressman Larry McDonald takes on Pat Buchanan and Tom Braden on Crossfire as they badger him about his new role as Chairman of the John Birch Society. He easily handles them and answers questions concerning the Elite's Conspiracy for a One World Government.
He was murdered for his public views
I think this a long forgotten but important video
worth the watch
