"I'm a journalist. But I'm an advocacy journalist, or an opinion journalist.") Hannity also appeared in a 2016 Trump campaign ad. Hannity has feuded with several conservatives who oppose Trump, including National Reviews Jonah Goldberg, Wall Street Journal foreign affairs columnist Bret Stephens, and National Review editor Rich Lowry. Conspiracy theories During the 2016 presidential election, Hannity periodically promoted conspiracy theories regarding Hillary Clinton and the Democratic Party. Hannity repeatedly claimed that Clinton had very serious medical problems and that the media was covering them up. He misrepresented photos of Clinton to give the impression that she had secret medical problems. He shared a photo from the fake news site Gateway Pundit and falsely claimed that it showed her Secret Service agent holding a diazepam pen intended to treat seizures, when he in fact was holding a small flashlight.

In May 2017, Hannity became a prominent promoter of the conspiracy theory that Hillary Clinton and the Democratic Party had a DNC staffer killed. Shortly afterward, he faced backlash from news sources across the political spectrum and lost several advertisers,
