Brand of the day: Fox News

Following the broadcaster's GOP debate last night (6 August), presidential hopeful Donald Trump blasted the channel for putting questions to him that were "much tougher" than those asked of the other candidates.

"The questions to me were not nice. I didn't think they were appropriate. And I thought Megyn [Kelly] behaved very badly, personally," he added.

The first debate between the Republican candidates (including Jeb Bush and Rick Perry), focused on a wide range of issues from ObamaCare to the US' dealings with Iran.

Defiant Trump stood by offensive comments he has made in the past about women. When host Kelly pointed out that Trump had called women "fat pigs, slobs, disgusting animals" on Twitter, he interrupted her to smirk and say "Only Rosie O'Donnell".

He also took to Twitter after the show to remark on the channel's analyst Frank Lutz, saying that he was "a low class slob who came to my office looking for consulting work and I had zero interest. Now he picks anti-Trump panels!”

Fox News, owned by Fox Entertainment Group, has been accused of leading its coverage with a conservative bias – calling into question its motto: 'Fair & Balanced'.

The channel was launched by Rupert Murdoch, who hired former Republican Party media consultant and NBC executive Roger Ailes as its founding chief executive in 1996.

One of its most popular hosts, Bill O'Reilly has courted controversy on several occasions, from shouting at Jeremy Glick (a man who lost his father in 9/11), to ranting on air about his strict views on same-sex marriage.

At the start of this year, the news provider was criticized when a presenter claimed that Birmingham in the UK was a “Muslim-only city”.

Steve Emerson, speaking about the Charlie Hebdo attacks, said that there are "no-go zones" throughout Europe where "non-Muslims just simply don’t go."

The wildly incorrect claim sparked a social media movement ridiculing the comments using the hashtag #FoxNewsFacts.

Despite the mogul's criticisms, Trump came out on top of last night's panel according to polls.

Fox5's latest vote shows that 50.6 per cent of viewers believe that the entrepreneur won the debate.
