WHAT THE PAGES KNEW ex-Page Tyson Vivyan, on what he told the FBI: “I began to describe basically the beginning of what turned out to be an almost surrealistic relationship with Congressman Foley through the instant messaging system online. It began shortly after I left the page program. … I was I.M.’ed by a screen name which I did not recognize, and almost immediately the conversation turned sexual.”
Asked how Foley got his IM: “That’s the question at hand. The pages, they’re on the Hill, walking around with name tags on that say U.S. House of Representatives page, with our first and last names spelled out completely. And so I can only assume that perhaps, if anyone caught the congressman’s eye, he could very easily make note of that individual’s name and then through a simple search online, if an individual such as myself decided to use my full name in our chat profile.”
More: “There was a moniker by which we described Foley. It was F.F.F. … that stands for Foley the f– from Florida. And it was kind of a running joke” (“O’Reilly Factor,” FNC, 10/3).
