Fox News host Sean Hannity took a swipe at his colleague Megyn Kelly after she called out Republican presidential nominee Donald Trump for retreating to Hannity's show and avoiding interviews with other media outlets and interviewers. Hannity almost immediately lashed out at Kelly on Twitter by calling her a Clinton supporter. 

Kelly noted on her October 5 show that Trump “will go on Hannity and pretty much only Hannity, and will not venture out to the unsafe spaces these days, which doesn't exactly expand the tent for either one of them.” 

Almost immediately, Hannity tweeted back to Kelly: 

@megynkelly u should be mad at @HillaryClinton Clearly you support her. And @realDonaldTrump did talk to u. https://t.co/vsQiNMgHut

Kelly is correct: Trump has retreated almost exclusively to the Fox News bubble, with Hannity largely being his go-to show. As CNN's Brian Stelter wrote, Trump is likely avoiding other networks to limit his “exposure to hard-hitting questions.” Trump's insistence on staying in the Hannity cocoon is no surprise, given that Hannity has been one of his biggest cheerleaders throughout the election, using his prime-time show to openly shill for Trump and advance his lies. Hannity also gave Trump far more interview airtime than other GOP presidential candidates during the Republican primary.
