Here's but a few of the many "sources" my friend:
Lisa Lerer (AP) writing an article about Clinton's "Wall Street problem" and "she is asking if we wish to characterize her remarks in any way."
/podesta-emails/emailid/36373
DNC & Clinton campaign staff being given the opportunity to provide CNN with questions to ask Trump in an upcoming interview.
/dnc-emails/emailid/27526
Mark Leibovich (NYT) allowing clinton campaign to edit his article - they're literally picking what to include and what not to include in the article.
/podesta-emails/emailid/4213
DNC staff saying Kenneth Vogel (Politico) gave her his story in advance (per an agreement?), and that if there's anything the Clinton campaign doesn't like, she can "push back".
/dnc-emails/emailid/10808
Campaign staff discussing how to push back against successful Sanders attack of showing Clinton as being the "establishment" candidate. The strategy involves getting bloggers and columnists to "write about this from a racial justice and reproductive rights perspective, including a few people who joined us on a call to talk about the "Bernie Backlash" that was unfolding even before his remarks last night—current list is Elianne Ramos [HuffPo], Jessica Valenti [Guardian] (who is writing a column on this as we speak), Jamil Smith [MTV/Viacom], Sady Doyle [Guardian, The Atlantic], Aminatou Sow, Gabe Ortiz [WaPo, Univision], and others".

And of course we can't forget Donna Brazile getting caught red handed giving debate questions in advance...
Of course it would be foolish to expect corrupt media cronies, who socialize and schmooze regularly with a certain candidate's campaign staff, to expose their own corruption.
