NEW YORK – Sean Hannity has hurled what many of his Fox News Channel viewers would consider an insult at colleague Megyn Kelly: He accused her of being a Hillary Clinton supporter.

Hannity reacted by Twitter on Wednesday night after Kelly had a segment on her show about the presidential candidates tightly controlling press access. She noted that Republican Donald Trump “will go on Hannity and pretty much only Hannity and will not venture out to unsafe spaces these days.”

Hannity responded on Twitter, writing “u should be mad at @HillaryClinton. Clearly you support her. And @realDonaldTrump did talk to u.” When another Twitter user told Hannity he should stand by his colleagues, the host said, “Sure. When they stand by me.”

Trump has been a frequent Fox guest in recent months, particularly on Hannity and the morning “Fox & Friends” show. Hannity, a conservative talk-show host, has said he supports Trump and has given him campaign advice. He appeared in a Trump campaign video without his network’s knowledge, but was told not to do that again.

Trump’s rocky road with Kelly, dating to the first GOP primary debate in summer 2015, is well documented. He did appear as an interview subject on a Fox broadcast network special done by Kelly in the spring.

Kelly had no response to Hannity on social media. Fox representatives had no immediate response to requests for comment Thursday.
