Thousands in US capable of killings, says Donald Trump

Donald Trump says there are thousands of people living in the US “sick with hate” and capable of carrying out the sort of massacre that killed at least 50 people in a Florida nightclub.

“We can’t let people in... We have to be very, very strong,” the presumptive Republican presidential nominee said.

“The problem is we have thousands of people right now in our country. You have people that were born in this country who are susceptible to becoming radicalised,” the billionaire told Fox News Channel’s Fox & Friends.
