Donald Trump has claimed his policy platform could have prevented the 9/11 terrorist attacks on the United States because his immigration plan would have stopped Muslim hijackers from entering the country.
The Republican candidate also reportedly claimed Hillary Clinton was the 'founder of ISIS' during his speech to a party event in Daytona Beach, Florida, on Wednesday.
In of his most controversial comments to date, Mr Trump had pledged to ban all Muslims - 1.6 billion people worldwide - from entering the US.
However, this policy has since been clarified to include only immigrants from so-called 'terror states'.
His immigration plan also involves building a massive wall to stop illegal immigrants along the country's southern border with Mexico - and make Mexico pay for it
ABC News reports that Mr Trump - declaring his campaign more united than ever amid reports it was in chaos - used the rally on Wednesday to set out how the immigration policy would have influenced America had he been president back in 2001.
'Those people that knocked down the World Trade Center most likely, under the Trump policy, wouldn't have been here to knock down the World Trade Center,' Mr Trump said.
However, Mr Trump and his campaign has appeared to soften the stance in recent months with clarifications.
In May and early June, Mr Trump described the ban as temporary. He later tweeted, in late June, a further clarification.
'We must suspend immigration from regions linked with terrorism until a proven vetting method is in place,' he said.
The website reported the latter proposal stopped short of the original blanket ban and appeared to exempt the countries where the 9/11 hijackers hailed from - Saudi Arabia, Egypt, the United Arab Emirates, and Lebanon.
The ABC network reported Mr Trump also used his speech to claim that Mrs Clinton deserved an award because she was 'the founder of ISIS.'
'Wouldn't that be embarrassing to lose to crooked Hillary Clinton?' Mr Trump said.
'That would be terrible.'
