I don't know if this has been revealed or not, but I'm going to post this.
Think Progress has found an article from the
New York Daily News saying that NRCC chairman Tom Reynolds accpted a $100,000 contribution from Mark Foley. Reynolds was apparently informed of Foley's emails sometime around Feburary of 2006. Was this some form of blackmail? I don't know. But it is certainly very suspicious.
Here's the link to the FEC Schedule B form.
Here is
the search result for the campaign contributions received by the NRCC. Most of the contributions vary between $1,500 to 25,000. Although there are a couple of other $100,000 contributions included besides Foley's contribution.
