I have been told by another freeper than Weldon has never mentioned The Wall or firewall.
Has Weldon actually mentioned The Wall?
Yes., he did, perhaps not using the word wall, but in a letter to committee members he did talk about somewhere from i998 - 2000 it was made impossible to share information.
If you care to read the letter, go to the world net daily web site, and in search type Curt Weldon.
