At an appearance in Iowa, Romney made a comment -- directed at Rudy Giuliani -- that the former mayor “instructed city workers not to provide information to the federal government that would allow them to enforce the law. New York City was the poster child for sanctuary cities in the country."

When asked about the comments in Manhattan today, Bloomberg said, “Boy, let ‘em come.” He went on to say, ““This city and this country were built by immigrants. Thrive on immigrants. And without more immigrants we don’t have a future.”
