Donald Trump spoke with Piers Morgan on 'Good Morning Britain' on Wednesday.
"When they see trouble, they have to report it. They are not reporting it; they are absolutely not reporting it, and that’s a big problem," Trump said about Muslims living in the U.S. and Britain.
"It’s like they’re protecting each other, but they’re really doing very bad damage, and they have to open up to society," Trump continued. "They have to report the bad ones."
