'Is that the dumbest thing you ever heard?' Trump lashes out at Hillary for saying his temporary Muslim ban would make him a 'recruiter' for more terrorism

Donald Trump fired back at Hillary Clinton Thursday night and Friday morning following her claim that his proposal to temporarily ban non-citizen Muslims from entering the U.S. would backfire and serve to enlarge the global terrorism problem.

'Is that the dumbest thing you ever heard?' Trump asked the hosts of 'Fox & Friends' on Friday morning.

'To me it's one of the dumber statements I've ever heard. I mean, she's so ill-equipped to be the president!'

'I just think it's absolutely dumb,' he added.

Clinton had told CNN on Thursday that Trump's December 2015 proposal – which he later framed as a speculative suggestion – made him 'a recruiter for more people to join the cause of terrorism.'

'When you run for president of the United States, the entire world is listening and watching,' she said. 'So when you say you're going to bar all Muslims, you're sending evidence to the Muslim world, and you're also sending a message to terrorists.'

In a statement Thursday evening, the billionaire shoved back – hard.

'The fact that Hillary thinks the temporary Muslim ban, which she calls the "Muslim ban", promotes terrorism, proves Bernie Sanders was correct when he said she is not qualified to be President,' he said in a statement released by his campaign.

'Look at the carnage all over the world including the World Trade Center, San Bernardino, Paris, the USS Cole, Brussels and an unlimited number of other places.'

'She and our totally ignorant President won't even use the term Radical Islamic Terrorism,' he said in the taunting declaration. 'And by the way, ask Hillary who blew up the plane last night - another terrible, but preventable tragedy.'

'She has bad judgement [sic] and is unfit to serve as President at this delicate and difficult time in our country's history.'

Trump said Thursday that anyone who doesn't think the EgyptAir got blown up is '100 per cent wrong'

Appearing at a fundraiser for his formal rival Chris Christie – now an endorser – Trump referenced the Egypt Air passenger jet that crashed in the Meditteranean Sea on its way from Paris to Cairo, and slammed Clinton for refusing to utter the words 'radical Islamic terrorism.'

'She refuses to use that term,' he marveled. 'I'm saying to myself, what just happened about 12 hours ago? A plane got blown out of the sky and if anybody thinks it wasn't blown out of the sky – you're 100 per cent wrong, folks.'

On 'Fox & Friends,' he said proposing to shut America's borders to Muslim travelers who haven't been vetted would produce 'just the oppposite' of Clinton's predicted outcome.

Muslim-Americans, he said, would feel pressure to police their own communities and 'turn in the people that are bombing the planes.'

'When you run for president of the United States, the entire world is listening and watching,' Clinton said

'And they know who the people are,' he insisted.

'They are going to have to start turning in – you take a look even at San Bernardino. Everybody knew that they were going to do this attack! There were bombs all over their apartment. Everybody saw the bombs. They knew this was happening. And nobody turned them in,' an exasperated Trump insisted.

'And you take a look at Paris. Everybody knew what was happening. And by the way, the last person that they were looking all over for, for eight months, they found that person living practically where he lived before! Nobody turned him in!'

Trump also claimed the ISIS terror army would take advantage of the United States if a weak leader were in charge beginning in 2017.

'We can't afford to be so nice and so foolish anymore. Our country's in trouble,' Trump said. 'ISIS is laughing at us, and they see somebody like Hillary Clinton who reads off her teleprompter.'

'The whole thing is so insane, so we're going to have to get very tough and very smart,' he said. 'And Hillary Clinton can never get you there. It's four more years of Obama and this country can't take it.'
