Less than 24 hours than reality TV star and Republican candidate Donald Trump said he would ban all Muslims from entering the United States, he now struggling to explain how his policy would play out.

During an interview with MSNBC’s “Morning Joe,” he doubled down on his comments made on Monday night.

"They would say: 'Are you Muslim?'" Mr Trump explained on Tuesday.

"And if they said, 'yes,' they would not be allowed in the country?" Co-host Willie Geist asked.

"That's correct," Mr Trump said. He added that family members of Muslim families would be forced to turn in those close to them who are "acting suspicious."

He then refused to answer anymore questions regarding the subject, the Washington Post reports, likely because most Republicans, Democrats and the White House had condemned Mr Trump’s rhetoric as quickly as the words came out of his mouth.

Later, Mr Trump continued his tirade — that's earned him comparisons to Adolf Hitler — by implying that the Muslim ban would prevent tragedies similar to the September 11 attacks.

"You're going to have many more World Trade Centers if you don't solve it — many, many more and probably beyond the World Trade Center," Mr Trump said during an interview on CNN.

"They want our buildings to come down; they want our cities to be crushed," he said. "They are living within our country. And many of them want to come from outside our country."
