And the wheels are off the bus. Boehner says Hastert knew about the investigation, and told Boehner "we're taking care of it." From the Washington Post:

The resignation rocked the Capitol, and especially Foley's GOP colleagues, as lawmakers were rushing to adjourn for at least six weeks. House Majority Leader John Boehner (R-Ohio) told The Washington Post last night that he had learned this spring of some "contact" between Foley and a 16-year-old page. Boehner said he told House Speaker J. Dennis Hastert (R-Ill.), and that Hastert assured him "we're taking care of it."

As I said in comments below, Hastert's toast. If he can survive this with his leadership position intact, it will only be because the GOP is so riddled with corruption that it has literally nobody else to fall back on.

You don't protect a sexual predator using the tools of your office. No, not even if you're a Republican.
