I read between the lines that they are going to investigate THE SOURCE of the document. Looks like they tried to bury that fact in a bath of BullHockey. But everything in this article points to an investigation of where the document originated. Which could be VERY interesting indeed. There was some speculation that this document could be linked to the international seditionist leftist groups, such as the democrat party or groups linked to moveon.org.
Look for followups to this story on page A12 below the fold.
You are correct -- if you look at the story and throw out the LA Times spin you see that the FBI is now investigating the forged documents and just maybe since the WH is on the offensive the reason for Wilson going to Niger and the follow-up will be released.
