Who is investigative JOURNALIST checking allegations Hillary will "smear" Obama Oct 28, just B4 Nov election?

This is a nasty rumor - is it true? Who (do we know?) is checking "gossip" inside her campaign to verify what they plan or have asked others to do or had "volunteered" to Clinton already? A late night revelation of a love child or teenage "record" or some such could derail Obama's nomination. Hope they close all the dirty tricks teams hard at work now!
