Following an ISIS-related attack at a Christmas market in Berlin this week, Mr Trump renewed his calls to carry out sweeping discriminatory acts against Muslims from overseas and the American Muslim population which is around 3.3 million people.
Trump said "You know my plans all along and I've been proven to be right," he told reporters at his Mar-a-Lago resort in Florida.
Mr Trump was speaking the day after a man hijacked a lorry, killed the driver and ploughed into a Christmas market, killing at least 12 people and injuring 48.
Mr Trump was also referring to the Russian ambassador to Turkey who was killed in Ankara.
"It's an attack on humanity and it's got to be stopped," Mr Trump added.
The president-elect had been seen to backtrack on his hard-line anti-Muslim stance when his December 2015 statement pledging to temporarily suspend Muslim immigration disappeared from his website the day of the election.
"Donald J Trump is calling for a total and complete shutdown of Muslims entering the United States until our country's representatives can figure out what is going on," he said at the time.
"When I am elected, I will suspend immigration from areas of the world when there is a proven history of terrorism against the United States, Europe or our allies, until we understand how to end these threats," Mr Trump said in a June 2016 speech.
He then changed his policy to only suspend immigration from countries that have been compromised by terrorism, rather than discriminating against one religion which claims more than 1.6 billion people.
Mr Trump first called to ban Muslims shortly after the terrorist attacks in Paris in November 2015. With every Isis-related assault, Mr Trump tweeted that he would be "tough, smart and vigilant".
A week after the election, Kansas secretary of state and Trump adviser Kris Kobach revealed the team were looking at ways to implement a registry.
Mr Trump has never clarified exactly how he would plan to execute the controversial policies.
Mr Trump's communications director, Jason Miller, denied that his boss had ever advocated for a Muslim registry.
Since his election, the Council on American-Islamic Relations has reported at least 900 hate crimes against Muslims across the country, from mosques being vandalised and set on fire, to Muslims being beaten, shot and stabbed on the street.
