Two hosts from the American news network Fox News have clashed over Republican presidential candidate Donald Trump's media appearances, with one saying Trump only picks interviews with her Trump-supporting colleague.

Megyn Kelly took aim at both presidential candidates in a segment on her show saying that both are in their own "presidential protection program" by only picking "safe" media appearances. Kelly criticised Democratic candidate Hillary Clinton for not going to places "where she feels uncomfortable" before saying that Trump only chooses to go on her colleague Sean Hannity's show.

"Donald Trump, with all due respect to my friend at 10 o'clock, will go on Hannity and pretty much only Hannity and will not venture out to the unsafe spaces," Kelly said live on the news channel.

Hannity then hit back at Kelly on Twitter, tweeting that she "clearly" supports Hillary Clinton and that Trump did talk to her.

It's not the first time Kelly has found herself at the ire of Trump supporters during this campaign. As reported in the Guardian, Trump took issue with her moderation of the first Republican primary debate, saying Kelly "had blood coming out of her eyes, blood coming out of her wherever" - in a comment widely construed to have been about menstruation.

The feud has continued since then with Trump calling Kelly 'Crazy Megyn' in a tweet and mentioning her in a tweet during the vice presidential debates.

Hannity, on the other hand, has expressed support for the Republican candidate and had him appear on his show a number of times. Hannity also appeared in a campaign video put out by Donald J. Trump For President.
