Presidential candidate Donald Trump has rekindled a feud with Fox News host Megyn Kelly, criticizing her in a series of messages when she returned to her show from vacation.

The business tycoon reposted another user's message on his Twitter account Monday night that said 'The bimbo back in town. I hope not for long."'

A barrage of tweets and retweets seemed to signal an end to the ceasefire of Trump towards Kelly, who the Republican had previously criticized as being unfair to him in the party's first debate earlier this month.

He told CNN that she had 'blood coming out of her eyes, blood coming out of her wherever' during the debate in Cleveland, which many interpreted as a veiled referenced to menstruation.

Trump later said that he was trying to say that blood was coming out of her nose or ears, and that only a 'deviant' would think otherwise.

Similar to Monday's messages, Trump also reposted a Twitter user saying that Kelly was a 'bimbo' in the aftermath of the debate.

In several interviews after the remarks he also said that he 'cherishes' women and would do more for them than other candidates.

A firestorm around the comments died down as early August progressed, when the Apprentice star and Fox News chairman Roger Ailes reportedly 'made up' and Trump said that the network would cover him 'fairly'.

However, the front-runner began criticizing one of Fox's most popular hosts again on Monday, saying 'I liked The Kelly File much better without @megynkelly. Perhaps she could take another eleven day unscheduled vacation!'

Hosts during Kelly's absence included other Fox anchors Martha MacCallum and Shannon Bream.

Trump also said Kelly 'is really off her game' and said she was afraid to confront liberal professor and activist Dr. Cornel West.

ROGER AILES' COMPLETE STATEMENT ON DONALD TRUMP 'Donald Trump's surprise and unprovoked attack on Megyn Kelly during her show last night is as unacceptable as it is disturbing. 'Megyn Kelly represents the very best of American journalism and all of us at FOX News Channel reject the crude and irresponsible attempts to suggest otherwise. I could not be more proud of Megyn for her professionalism and class in the face of all of Mr. Trump's verbal assaults. 'Her questioning of Mr. Trump at the debate was tough but fair, and I fully support her as she continues to ask the probing and challenging questions that all presidential candidates may find difficult to answer. 'Donald Trump rarely apologizes, although in this case, he should. We have never been deterred by politicians or anyone else attacking us for doing our job, much less allowed ourselves to be bullied by anyone and we're certainly not going to start now. 'All of our journalists will continue to report in the fair and balanced way that has made FOX News Channel the number one news network in the industry.' Advertisement

Kelly's vacation came right after the controversy over Trump's 'bloodgate' comments, with the anchor saying 'it's been an interesting week' and claiming she needed a vacation because she hadn't had one in six months.

Fox gave a statement to Mediaite about the vacation saying: The conspiracy theories about Megyn Kelly’s vacation rank up there with UFO’s, the moon landing and Elvis being alive.'

'Megyn is on a pre-planned, annual summer vacation with her family, which is much deserved.'

In addition to his messages about Kelly, Trump also reposted a user's message about Jeb Bush and immigration.

'Jeb Bush is crazy, who cares that he speaks Mexican, this is America, English !!" he posted with reference to another account.
