This morning's Scranton Times Tribune has an article about the "kill him" claim.
The Secret Service is investigating but the only person they can find that heard it is the Scranton Times reporter. Not one other person.
At this time (5 am) the article isn't on their web site, just the print edition.
Thanks for the ping. I’ve been thinking all along that this is a scheme by liberals.
The article link is at this thread’s article in Editor and Publisher. I read it, and it sounds as though someone was saying to kill Chris Hackett: http://www.thetimes-tribune.com/articles/2008/10/14/news/doc48f4ba8994588930223377.txt
