Newsweek puts first Fordham/Hastert's office contact in 2002 or 2003 about Foley: WaPo says Jim Kolbe knew in 2000

So, it seems that rumor about Mark Foley getting drunk and trying to get into the page dorm is more than a rumor. Kirk Fordham is going to tell the FBI that it was that incident that led to the 2002/2003 contact with Hastert's Chief of Staff. (Newsweek)

On one night in 2002 or 2003, an allegedly inebriated Foley showed up at the pages' dorm after a 10 p.m. curfew and tried to gain entry, according to an account provided by two congressional sources, who declined to be identified due to the sensitivity of the matter. Foley was turned away by a guard. It is not known if the pages were ever aware that Foley lurked outside their door, but word of the incident reached the House Clerk, who notified Foley's chief of staff, Kirk Fordham.

This was not the first time that Fordham had learned of his boss's behaving, in that modern all-purpose euphemism, "inappropriately." Fordham decided that it was time to go to a higher authority, so he went to see Scott Palmer, chief of staff to the Speaker of the House, Dennis Hastert.

(I'm guessing the source is the attorney or someone helping Fordham's side.)

Also: The WaPo has a story saying that Rep. Jim Kolbe (R-AZ) had knowledge of "sexually exlicit" messages from Foley back to 2000. Kolbe "personally confronted" Mark Foley about this.
