A CNN report  of August 29, 2002 -- available at

http://www.cnn.com/2002/US/08/29/intelligence.leaks.ap/index.html

indicates that the FBI is asking
Senate investigators to undergo polygraph examinations in regard
to the  leaks mentioned earlier in the thread.  This looks very much like a power struggle between the congressional and executive branches:
note that the executive branch (to wit, the FBI) appears to have recently given a sop to Congress in the "spontaneous" resignation of Dale Watson.  After that "carrot", now the
"stick" of polygraphing to impede and discredit further investigation of the background in the Edmonds case.
