As soon as Jack walked through the door, Globe and Mail reporter Marsha Lederman knew he was the man who claimed to be the "love child" of John F. Kennedy.

Jack contacted the Globe to get his story out on his own terms, after the New York Post broke the news last week that Vanity Fair magazine was working on an article about a Vancouver man who claimed to be the illegitimate child of the assassinated president.

Lederman told CTV's Canada AM she made plans to meet Jack in a public place and waited anxiously for him to arrive.

"I got there very early and I was watching everyone, scrutinizing everyone who was walking into this public area thinking 'is that him, is that him?' But as soon as he walked through the door I knew it was him. He certainly does bear a striking resemblance to John F. Kennedy," she said.

Jack, who has asked that his full identity not be revealed, told Lederman he came forward to avoid reporters trying to find him in Vancouver after a number of publications ran stories about him on Friday.

"He contacted me because he was worried about media hordes trying to track him down and felt he should take this step to go to a national publication, a publication he felt would treat his story with respect. And that's how I got a phone call from Jack on Friday," Lederman said.

The Post reported that Vanity Fair had been working on the story, but decided not to publish the piece after contacting the office of U.S. Senator Edward Kennedy, JFK's brother.

However the magazine said it would publish the story if it obtains proof, such as a Kennedy DNA sample that matches Jack's.

Lederman said he doesn't know whether Jack is in contact with the Kennedy family, or whether he has any relationship with them whatsoever.

"There were very few details that he would give me but he did say he is urging them to come forward with a DNA sample," she said.

"I don't know what kind of a relationship exists, if any, between this man and the Kennedys, whether they've actually had direct contact, but I assume that's why he came to me, to try to get the word out that he's looking for this DNA sample so there could be a match, potentially."

Jack read from a prepared statement during his meeting with the reporter.

"Vanity Fair needs help. We need JFK DNA and, barring that, DNA from any male Kennedy directly related to Joe Kennedy (JFK's father), either in the U.S. or Ireland (for a Y chromosome analysis),'' Jack read from a prepared statement.

Lederman said Jack was "well dressed, well heeled and wearing fine clothing" when they met in Vancouver, and maintained he is not coming forward with any aspirations of financial reward.

He said he even offered to sign an agreement with the Kennedy family to that effect.

"I told Vanity Fair that I would sign an agreement with the Kennedys immediately, in which I agree not to pursue any financial remuneration from the JFK estate whatsoever," Jack said.

"This isn't a story about the fairly silly, trivial 'discovery of JFK's illegitimate son,''' he stated.

He also said the information he would reveal could have a "potentially profound impact," though he wouldn't hint at what that could include.

"It's a question he said he's not prepared to answer quite yet but he indicated there's quite a bit there that is not apparent at the moment," Lederman said.

Jack, whom the New York Post says is in his late 40s, says he never met the man he claims is his father.

The Post describes his mother as being a Texan, but Jack revealed no details about her identity.

Jack told Lederman he recently moved to B.C., but was raised and educated in the U.S. and still holds American citizenship.

He said his wife is a Canadian, and they have children.
