The author of the hoax article was later identified as Brian Chase, an operations manager of Rush Delivery, a delivery service company in Nashville, Tennessee. On May 26, 2005, Chase added a new article that contained, in its entirety, the following text:
John Seigenthaler Sr. was the assistant to Attorney General Robert Kennedy in the early 1960s. For a short time, he was thought to have been directly involved in the Kennedy assassinations of both John, and his brother, Bobby. Nothing was ever proven.
John Seigenthaler moved to the Soviet Union in 1972, and returned to the United States in 1984.
He started one of the country's largest public relations firms shortly thereafter.
In his November 29, 2005, USA Today editorial, Seigenthaler criticized Congress for Section 230 of the Communications Decency Act, which protects ISPs and web sites from being held legally responsible for content posted by their customers and users:
And so we live in a universe of new media with phenomenal opportunities for worldwide communications and research – but populated by volunteer vandals with poison-pen intellects. Congress has enabled them and protects them.
In the CNN interview, Seigenthaler also raised the spectre of increased government regulation of the Web:
Can I just say where I'm worried about this leading. Next year we go into an election year. Every politician is going to find himself or herself subjected to the same sort of outrageous commentary that hit me, and hits others. I'm afraid we're going to get regulated media as a result of that. And I tell you, I think if you can't fix it, both fix the history as well as the biography pages, I think it's going to be in real trouble, and we're going to have to be fighting to keep the government from regulating you.
On December 9, Seigenthaler appeared on C-SPAN's Washington Journal with Brian Lamb hosting. He said he was concerned that other pranksters would try to spoof members of Congress or other powerful figures in government, which may then prompt a backlash and turn back First Amendment rights on the Web.
In the June 2007 issue of Reason magazine, Seigenthaler also expressed concern about the lack of transparency underlined by Wales' removal of the hoax pages from the article's history page. He has also stated that many of the comments left by users in the edit summaries are things he would not want his nine-year-old grandson to see.
