One of the implications in The New York Slimes story is that John Weaver, McCain’s chief strategist at the time, met with Iseman at Union Station in 2000, allegedly to tell her to end her a romantic relationship with McCain. Byron York has spoken to Weaver, who says this:

I just got off the phone with John Weaver, the former top McCain campaign official who is now an informal adviser to the campaign. I asked him about his 1999 meeting on the campaign’s behalf with lobbyist Vicki Iseman. He said he “had no reason to think” that McCain might have been having an affair with Iseman, but he was concerned about word he had heard suggesting that Iseman was telling associates she had connections with McCain. “This was a woman who was saying that she had special influence with John’s committee staff and with him,” Weaver told me. “I didn’t believe that was the case.”

“When you hear back from several people that this person is saying they can get anything done, then that is alarming,” Weaver continued. So Weaver met with Iseman, at a Union Station restaurant, and told her to back off. He told me he didn’t exactly say, “Get lost,” but that that was the gist of it. “The discussion lasted all of five or six minutes in which I told her to cut that stuff out,” Weaver told me. “I said, ‘You need to stop this.’” Iseman’s response, according to Weaver: “She was not happy.”
