And if you look a little harder, you will find he was claiming to be the leader in Jan 1993. We can't post the picture on here due to a copyright complaint, BUT...if you do a search on kERRY NIXON (all caps except the first letter, not sure why it works that way, but it does, maybe they are trying to hide it) at Corbis, it brings up a picture of Kerry watching TV. If you click the photo to bring up the larger image, it has the caption. It states the photo was taken January 24, 1973 in Lowell, Massachusetts. It also identifies him as a Vietnam vet and head of Vietnam Veterans Against the War. Be careful where you post it though...Corbis is known to be nasty about infringement.
I know about the leader info, the FBI files for Jan-Feb 1972 also refers to him as leader.
Go to number 21 in this post and do what he says.
