The presumptive republican candidate in the US presidential election, Donald Trump, has called on Muslims to work with the police and "turn people in".
In an interview with the UK's ITV, Mr Trump said he was not anti-Muslim, but "anti-terror".
He was reacting to remarks by UK Prime Minister David Cameron that he was "stupid, divisive and wrong" in calling for Muslims to be banned from the US.
Mr Trump made the call last year, when he was not the party's front-runner.
He insisted that when he called for an immediate temporary ban on Muslims being allowed into America, there had been criticism only from politicians. Millions of people from all over the world had called in, he said, saying "Donald Trump is right".
Asked whether he would re-phrase those comments in the light of the controversy they caused, Mr Trump said: "It got people thinking. Whether it's good for me or bad for me, I don't really care."
