Donald Trump has hit back at Mitt Romney in typically bombastic fashion, using playground innuendo to try and discredit his fellow Republican over his scathing attack earlier in the day.
In a press conference the floppy-haired conduit for nonsense talked of "damaged carpets", bragged about the size of his house and spoke of the marble which is being installed in his new hotel.
He addressed a speech made earlier in the day in which Romney called the party's frontrunner for presidential candidate "a phoney, a fraud" who is "playing the American public for suckers".
Romney drew criticism for making a drastic U-turn from his stance four years ago when he gained Trump's endorsement for the 2012 US election and praised his "extraordinary" abilities.
Trump said today: "I could have said, ‘Mitt drop to your knees,’ and he would have dropped to his knees.
"Mitt is a failed candidate - he failed. He failed horribly."
Romney's intervention is unlikely to change Trump's standings in the election race after he had a storming Super Tuesday.
The unpredictable billionaire businessman and reality TV star who began his campaign as a fringe candidate, won seven of the 10 states up for grabs - Georgia, Alabama, Massachusetts, Tennessee, Virginia, Arkansas and Vermont.
The success led to a surge in the number of Americans Googling "How to move to Canada".
Infamous for his calls to build a wall across the Mexican border to keep immigrants out, Trump may now have to consider building another in the north to keep emigrants in.
In the past week Trump failed to distance himself from the Ku Klux Klan, was mocked for having bad make-up and small hands by one of his main GOP rivals and drove a sitting Republican Senator to publicly contemplate quitting the party in protest at his candidacy.
