Fox bashes Trump over debate boycott
Fox News has fired back at Republican presidential candidate Donald Trump for his refusal to participate in their debate on Thursday night.
The network said in a statement that Trump's decision is "unprecedented" and accused him of "terrorising" debate host Megyn Kelly.
Trump clashed with Kelly at a Fox News debate last year and had demanded she be removed from Thursday's panel.
His decision to pull out has been mocked by his Republican rivals.
The debate is the final one before the first real test of the election campaign, the Iowa caucus on Monday when voters in the state pick their presidential nominee.
"Capitulating to politicians' ultimatums about a debate moderator violates all journalistic standards, as do threats," the Fox News network said in a statement.
"We're not sure how Iowans are going to feel about him walking away from them at the last minute, but it should be clear to the American public by now that this is rooted in one thing - Megyn Kelly."
It added: "We can't give in to terrorizations toward any of our employees."
Kelly accused the New York billionaire of misogyny in the first debate last August and he responded the next day by accusing her of having blood "coming out of everywhere". He denied he was referring to menstruation.
Trump, who leads the Republican field, quit the debate on Tuesday night after Fox put out a sarcastic statement that questioned his ability to deal with Russian President Vladimir Putin.
Fox responded by accusing Trump of "viciously attacking" Kelly, threatening her and spending four days trying to get her removed.
Republican presidential candidate Senator Ted Cruz mocked Trump for his announcement.
He challenged him to a one-on-one debate and taunted him on Twitter using the hashtag #DuckingDonald.
THE POLITICAL CLASS REACTS
MSNBC host and former Republican US representative Joe Scarborough said voters are seeing the billionaire at his "very best" and that Fox "made Trump look like the grown-up".
At the same network, Chris Matthews questioned "who's gonna watch the debate between the two Cuban guys?"
Republican political consultant Alex Castellanos said it showed that "Trump is playing on different level than the other candidates" and demonstrates "he is willing to take risks".
Republican political strategist Jeff Lord said Trump's decision was similar to Ronald Reagan's decision to walk "away from the negotiating table with Gorbachev at Reykjavik".
Political journalist Mark Halperin criticised Fox for taunting Trump and said the businessman would win by dominating the news cycle.
