Can you provide the RSVP log you're talking about? The only one I was able to find on a google search was
this one, which doesn't have any Fox News invites but also only has one each for CNN and MSNBC journalists and
does have three invites extended to the right-leaning, Murdoch-owned WSJ, a fact I notice you omitted from your rant. It also says that its simply a list of the reporters following the Clinton campaign via a particular bus, so it's clearly possible (likely?) that Fox News, which doesn't do a lot of investigative or beat reporting, simply didn't have anyone on that bus.
Is that the list you think is suspect? I'm not sure because you also described it as a "big kickoff party," and this is a 25 person dinner party, and I assume a stickler for transparency and veracity such as yourself would never post misleading information.
