After being slated by former Republican nominee Mitt Romney, Donald Trump has hit back with a bizarre blowjob joke.

Failed Presidential candidate Mitt Romney has warned that fellow Republican Donald Trump is not fit for the Presidential nomination.

In a speech on Thursday Romney, who lost to President Obama in the 2012 race, and previously in 2008, warned his party against nominating the Apprentice star as the candidate.

He branded Trump a “phoney” and a “fraud”, suggesting that Trump as President would be dangerous for the Republican party and the US.

Trump hit back, calling a news conference, and saying that Romney “begged” for his endorsement.

“I could have said, ‘Mitt drop to your knees,’ and he would have dropped to his knees,” Trump said. “Mitt is a failed candidate – he failed. He failed horribly.”

Going on, he said Romney “is a choke artist,” and of the 2012 race said it “should have been won”.

And a PinkNews edit – beware this cannot be unheard

Trump has told Fox News he would likely back a plot to overturn equal marriage, just days before telling the lesbian journalist he would “move forward” on LGBT rights.

When challenged on the contradiction in a third interview, Trump attempted to maintain both contradicting views simultaneously.

He promised evangelicals last month: “I think [evangelicals] can trust me on traditional marriage.”

Earlier this week, several media outlets called for New Jersey Governor Chris Christie to step down after he endorsed Trump.

Romney – who is strongly opposed to same-sex marriage –  last January revealed that he did not have plans to run for President for a third time.
