The pages were having an informal "mixer" party in their dorm at the Tip O'Neil building behind the Capitol, according to a former page who was 17 at the time.
"It was a beautiful summer evening, and I recall Mr. Foley arriving in his blue Series 3 BMW convertible about 9:30 at night," the former page said. "Several of us saw him and went outside to chat."
THE BLOTTER RECOMMENDS
A page program supervisor came out to warn the pages "not to go far because they weren't signed out" and shooed them back inside, he recalled.
The page supervisor was one of the adult staffers who worked for the House Clerk's office, which oversees the page program. It is not known if any formal report was filed regarding Foley's surprise visit. The former page, who spoke to ABC News on the condition he not be identified, said he then began receiving instant messages and e-mails from Foley which became sexually explicit immediately following his 18th birthday.
He said he has not retained any of the messages or e-mails.
"I would turn on my instant messenger, and he would be online at all hours of the day or night. The talk would quickly turn sexual," he said. He says Foley requested that he send photos of himself performing sexual acts.
According to Newsweek Magazine, it was the report of a similar nighttime visit by an inebriated Foley to the page dorm sometime in 2002 or 2003 that caused Foley's then Chief of Staff, Kirk Fordham, to alert Speaker Hastert's office to the congressman's inappropriate actions, a warning Hastert's office now says they never received.
