Donald Trump made the latest in a series of adjustments on Saturday to what has been referred to as his 'Muslim ban' policy, saying people from nations with high incidences of terrorism would be welcome in the U.S. during a Trump presidency – following nation-specific bans and a period when they are 'even more severely vetted' than other immigrants.

The billionaire real estate tycoon spoke with DailyMail.com exclusively on the 18th tee of his posh Trump International Golf Links Scotland, near the Aberdeenshire town of Balmedie.

Trump, the Republican Party's presumptive presidential nominee, set out a difference between what he called 'terror countries' and other nations, saying that after he applies a place-of-origin test to exclude people from terror-heavy nations, he would apply a steeper level of scrutiny to their homelands before beginning to admit them.

Separately, a campaign aide confirmed that Trump no longer supports a temporary blanket ban on Muslims entering the country.

And when a CBS News reporter asked him if Muslims from Scotland would be welcome in the United States, he responded: 'Wouldn't bother me.'

Trump said June 13 in a New Hampshire speech that 'when I’m elected I will suspend immigration from areas of the world where there’s a proven history of terrorism against the United States, Europe or our allies until we fully understand how to end these threats.'

Stephen Miller, Trump's top policy adviser, said late Saturday night in an email that the candidate's official policy was 'exactly what's in the speech.'

He specified a 'temp[orary] suspension [of immigration] from countries with terrorism concerns.'

Asked to reconcile that with Trump's outline of a looser policy, Miller seemed to suggest the two would run in sequence, with a 'pause from certain regions until [there is] effective security in place.'

Asked how he would distinguish a 'terror country' from safer locales, Trump waved his hand to brush off the question.

'They're pretty well decided. All you have to do is look!' Trump said.

'They're pretty well decided. I mean, people are looking at certain countries, and they're pretty well decided already.'

The newly refined policy itself, despite the ambiguity of which countries would qualify, is not markedly different from existing U.S. rules.

The State Department is already empowered to consider where an immigrant or visa-holder comes from when deciding whether to admit him or her into the U.S. and under what conditions.

'Everybody has to be vetted ... whether it's here or anywhere,' Trump emphasized on Saturday. 'They have to be vetted. They have to be vetted strongly.'

A real-time development seemed to occur in his mind as he played out how to reconcile a policy plan that some have called an arbitrary preference of some ethnicities and religions over others.

'I don't want people coming in from the terror countries. You have terror countries!' he said – before altering his view significantly.

'I don't want them, unless they're very, very strongly vetted,' he declared.

'In any case,' Trump said, emphasizing the word 'any,' 'we don't want people coming in unless they're very strongly vetted.'

He finally settled on saying 'I don't care where' immigrants come from.

'But they're going to be even more severely vetted if it's one of the terror countries.'

However he slices it, the question of which nations qualify as 'terror countries' could be an especially thorny one for a President Trump.

The State Department has just three nations – Iran, Sudan and Syria – on its list of 'state sponsors of terrorism.' But scores of other nations, most notably Arab states, have seen terror attacks linked to Islamic militants.

The U.S. itself was hit by a jihadi attack this month in Orlando, Florida, when an armed terrorist killed 49 people in a gay nightclub.

The FBI now says there is no evidence the mass-murderer was gay himself, suggesting that it was a less complicated Islamic terror attack.

And some nations in Europe have seen terror attacks as well, including last year's Paris attacks and he '7/7' London bombings in July 2005.

Trump wouldn't say that he considers any European nation to be a 'terror country.'

When he was reminded that the French have endured deadly attacks from Muslim extremists, he said: 'You're right.'

'They have terrorist problems all over,' Trump sighed.

The brief interview came after Trump landed his helicopter on the 10th fairway of his golf course and took reporters on a tour of two iconic holes.

He drove his granddaughter Kai from hole to hole in a golf cart.

FRIENDS OF THE DON: Publishing tycoon Rupert Murdoch and his wife, former model Jerry Hall, joined Trump for dinner in Aberdeenshire on Saturday

'I have Rupert Murdoch coming for dinner tonight,' he told DailyMail.com – and then shouted to his press secretary Hope Hicks.

'Did you mention that, Hope? Spread it!' he yelled.

Murdoch's family roots are in Scotland's northeast. His grandfather emigrated from near the Aberdenshire golf course, moving to Australia.

The publishing magnate arrived at the golf course around 5:15 p.m., riding to the clubhouse in an SUV with Trump at his side.
