Presumptive Republican presidential nominee Donald Trump is asserting there are thousands of people in the United States "sick with hate" and capable of committing the kind of shooting rampage that killed at least 50 people in a Florida nightclub.
Trump also says Muslims in this country know who these radicals are and "should turn them in" to authorities.
The billionaire real estate mogul told Fox News Channel's "Fox & Friends" he believes "there are people out there with worse intentions" than the shooter in Orlando. He claimed that there are "thousands of people" in this country who are subject to becoming "radicalized."
Trump has changed the focus of a planned speech Monday to discuss terrorism.
"It's not easy, but we have to be very, very strong," he said.
