It's worse than you know. a few months back Doug "Hagman did a dig and exposed it on his morning show.
Records of the list of the Communist Infiltrators exposed by McCarthy and more were dissapeared in the early 90's from the Natiopnal Archive, AND a secondary location at a library in Virginia. Under the Clintons. no one knows where they are and some of it is probably lost forever.
These were the lists of names that could be used to track the infiltration to current bad actors today.
I want to say it aired in dec or Jan, but may have been oct or nov.
