"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," Trump said in CNN's morning news program.
On Monday, Trump called on the United States to deny the entry to the country of all Muslims until a counterterrorism plan is established.
White House deputy national security adviser Ben Rhodes said later on Monday that Trump’s suggestion is "totally contrary" to the US values.
Another Republican presidential contender, Senator Lindsey Graham, slammed Trump’s ideas on Tuesday.
“He doesn’t represent my party, he doesn’t represent the values that the men and women in uniform are fighting for,” Graham said on the same CNN news program. “He is the ISIL [Islamic State] man of the year, by the way.”
Trump has made numerous controversial statements about Muslims during his presidential campaign. In November, he said on two separate occasions that they were celebrating the September 11, 2001, extremist attacks in the United States and proposed a mandatory database of Muslims.
