Krauthammer Explains How 'British Independence' Will Break Up the UK

Bill O'Reilly phoned into The O'Reilly Factor tonight to weigh in on the Brexit. He said the vote was about "immigration" and "open borders."

O'Reilly said that over the past 30 years, a lax immigration policy has allowed so many people into the UK who haven't assimilated with British culture.

"If you go to parts of London, you're not really in England, you're in Pakistan. Or you're in the Middle East, or you're in the West Indies. And everybody knows this." 

O'Reilly said that the English people have said, "You know what? Enough. We're not feeling comfortable with being overwhelmed and we are feeling under siege."

He added that he didn't think the Brexit had anything to do with the economy, saying "it was all about immigration."
