It's been a turbulent time for Fox News lately, and soon the network may be seeing another big change. On Tuesday, primetime host Sean Hannity tweeted about his future at Fox News, promising a "huge announcement" and prompting many to wonder if he'd be leaving the network. While nothing is certain yet, Hannity has come under fire in recent days for promoting a controversial story about murdered DNC staffer Seth Rich.

Early in the evening, Hannity tweeted, "Huge announcement tonight about Seth Rich, Trump/Russian Collusion corrupt media [sic], the liberal effort to silence me. And my future at Fox!" The story in question is an unproven conspiracy theory about Rich, who was shot last July in Washington, D.C., in what local police say seems to be a robbery gone wrong. However, some in the conservative media have been pushing the unfounded theory that Rich had provided DNC memos to Wikileaks, and that he may have been killed in retribution. There is no evidence to support the Seth Rich conspiracy theory, and a recent Fox News story claiming to have found some proof fell apart hours after it was published.

The network later retracted the story, but Hannity continued to peddle the theory on social media, despite the Rich family begging him to stop, and Fox News staffers expressing to CNN that they were reportedly "disgusted" by Hannity's continued promotion of it. Hannity did not immediately respond to Romper's request for comment.

Of course, Fox News is no stranger to keeping on controversial figures, at least for a time. So while the handling of the Rich conspiracy theory has added fuel to the rumors that Hannity might leave the network, it didn't start them. The Daily Beast reported at the beginning of May that, according to sources, Hannity was thinking of exiting the network after his ally, Fox News co-president Bill Shine, resigned over allegations that he had enabled both Fox News creator Roger Ailes and host Bill O'Reilly in decades of sexual harassment at the network. Before Shine's resignation, Hannity tweeted that his departure would be "the total end of FNC as we know it."

If Hannity does leave, he'll be the latest big name to exit the network, following O'Reilly's recent departure. Still, according to The Los Angeles Times, insiders don't expect Hannity to leave Fox, where he reportedly makes more than $10 million a year.

Times are a-changing at Fox News. But, unfortunately for those who believe that news hosts should not spread painful misinformation, Hannity might be staying the same.
