So what?
Anything can be read into the Congressional Record.
What was it? Who read it? What was the source for it BEFORE it was read into the Congressional Record?
It was NOT from the USSR - some secret cabal uncovered and decoded - it was from the author of a book The Naked Communist by Cleon Skousen - who had no particular knowledge of the goals and aspirations of the USSR - but DID want to associate anything he personally opposed with Communism (i.e. civil rights, anti-colonialism, freedom of religion, etc).
So you want to change the definition of treason given in our Constitution to cover just about any action or non-action that might further the goals of our enemies based upon a not credible Mormon author's made up list?
Yeah - that is rational - in LooneyTune Cartoon Constitution land!
