I think Camil was at a Vietnam Veterans for Kerry thing in Gainesville, but no official campaign connection.

When questions were raised last month about whether a 27-year-old John Kerry had attended a Kansas City meeting of Vietnam Veterans Against the War where the assassination of senators was discussed, the Kerry presidential campaign went into action.
It accepted the resignation of a campaign volunteer in Florida, Scott Camil, the member of the antiwar group who raised the idea in November 1971 of killing politicians who backed the war. The campaign pressed other veterans who were in Kansas City, Mo., 33 years ago to re-examine their hazy memories while assuring them that Mr. Kerry was sure he had not been there.
