The report released by Pat Roberts' Senate Intel. Committee did not address it, in fact there is a footnote in the report explaining why this is:
"The documents from the Italian journalist are those that were later passed to the IAEA and discovered to have been forged. In March 2003, the Vice Chairman of the Committee, Senator Rockefeller, requested that the Federal Bureau of Investigation (FBI) investigate the source of the documents, ,the motivation of those responsible for the forgeries, and the extent to which the forgeries were part of a disinformation campaign. Because of the FBI's investigation into this matter, the Committee did not examine these issues."

You may want to ask his office to ask him to investigate this matter.
