This election has sparked some heated exchanges between family, friends and co-workers — and now between Fox News hosts.

Conservative pundit Sean Hannity leveled what he might consider the worst insult imaginable at anchor Megyn Kelly in a tweet Wednesday night, which said she "clearly" supports Hillary Clinton.

The tweet was apparently in response to Kelly comments earlier in the evening on The Kelly File when she accused both presidential candidates of avoiding tough interviews.
