So if there is anything close to a "party line", this would be it. Notice this whopper of a press release issued issued at 1:47 PM EDT by Media Matters, mere hours after this story hit the wires.

Relevant talking points:

Para 1: "A Washington, D.C., Fox News affiliate’s** shoddy reporting purposefully validated right-wing conspiracy theories about the murder of Democratic National Committee staffer Seth Rich when the station published unproven claims that Rich directly communicated with WikiLeaks regarding the leaked committee emails published on that site. **Following the publication of the Fox 5 DC story, Fox News hosts Bret Baier and Sean Hannity further fueled the conspiracy theories when they retweeted new conspiracies about the Rich story, including a false claim that a Washington Post report on Trump sharing classified information with Russia was published to drown out Fox 5's story."

Pretty much every paragraph here is a rebuttal of every source which reported on this story. The claims made in this article are identical to those of the Comet Ping Pong story. I predict this story will reach the thunderous roar of FAKE NEWS HURTS EVERYONE within a couple more days. Or it may just disappear like everything else.

Interesting Posobiec tried to ask about the murder (see video at bottom).

Note 1: Even Snopes says it is "unproven": http://www.snopes.com/seth-rich-dnc-wikileaks-murder/
