Fox News didn't deliver on its promised Seth Rich coverage investigation, so Media Matters is doing it instead. This is the fourth in a series marking the two-year anniversary of Fox’s publication of a story -- retracted seven days later -- that promoted the conspiracy theory that the murdered Democratic National Committee staffer, and not the Russians, had provided the DNC emails to WikiLeaks. Read part one, part two, part three, part four, and our timeline of events.

No one has been held accountable for Fox News’ promotion of conspiracy theories about murdered Democratic National Committee staffer Seth Rich.

Thursday marked the two-year anniversary of Fox News’ publication of a dubiously thin, hastily edited article pushing the debunked claim that Rich had provided DNC emails to WikiLeaks. After the story crashed and burned, Fox retracted it and promised to investigate what happened.

With no explanation forthcoming and no punishments announced two months after the story’s retraction, some Fox staffers voiced their displeasure to CNN’s Oliver Darcy. One Fox staffer told CNN that “people need to start getting canned” over the story.

But another senior Fox News employee quoted in the story was more resigned about the situation, arguing that the lack of transparency and accountability was unsurprising for the network: “No one ever gets fired from Fox for publishing a story that isn't true.”

The more cynical Fox staffer was correct.

Two years later, no one involved in producing or pushing the retracted Rich story has been publicly disciplined, and several have actually been promoted.

It’s clear, as the anonymous senior Fox employee indicated, that the network has no interest in journalistic integrity or employee accountability. The purported “investigation” was a scam intended to make it look like Fox was taking its responsibilities seriously until the anger over its actions dissipated.

Here is what has become of the network’s conspiracy theorists:

Malia Zimmerman is the investigative reporter who wrote the original FoxNews.com story that the network later retracted. She still apparently works at the network but has not published a new story since August 2017, soon after she and the network were sued over the story.

Greg Wilson, then deputy managing editor of FoxNews.com, reportedly edited Zimmerman’s story, rushing to publish it in spite of its flaws because a rival story on the subject was going viral. One month after the story’s publication, Fox promoted him to managing editor of FoxNews.com.

Sean Hannity, one of the network’s star prime-time hosts, championed the Rich conspiracy theory on Fox long after the story had collapsed. Some Fox employees told The Daily Beast they were embarrassed by his antics and network executives reportedly directed him to stop talking about Seth Rich after he lost advertisers and jeopardized a major acquisition deal in the U.K. But he has retained his show, which moved to the more coveted 9 p.m. timeslot later that year, continued to show disregard for anything resembling journalistic ethics and pushed conspiracy theories about how WikiLeaks obtained the DNC emails as recently as this April.

Porter Berry, the executive producer of Hannity’s Fox show at the time, was the recipient of a letter from Rich’s brother Aaron who urged him to find “decency and kindness” and stop promoting the conspiracy theories. In August 2018, Fox promoted him to vice president and editor-in-chief of Fox News Digital, a role in which he oversees all of the network’s digital content, including FoxNews.com, FoxBusiness.com, and the Fox News apps.

Laura Ingraham, then a Fox contributor, suggested on-air that the Rich family was covering up his death for partisan gain. In September 2017, Fox announced that she would host her own prime-time show for the network.

Newt Gingrich, a Fox contributor, claimed on-air that Rich had been “assassinated” for giving WikiLeaks DNC emails. He has repeatedly refused to retract his despicable comments. He still has his Fox platform.

Fox correspondent Griff Jenkins, the hosts of Fox & Friends and Fox & Friends First, Fox Business host Lou Dobbs, senior judicial analyst Andrew Napolitano were among the on-air network personalities who pushed the conspiracy theories. None appear to have been disciplined in any way.
