MANCHESTER, New Hampshire (CNN) - Talking immigration reform, former New York Mayor Rudy Giuliani said the "organizing purpose should be that our immigration laws allow us to identify everyone who is in this country that comes here from a foreign country."
"They should have a tamper-proof ID card," he said at Tuesday's GOP presidential debate. "It should be in a database that allows you figure out who they are, why they're here, make sure they're not illegal immigrants here for a bad purpose."
"We can do that," added Guiliani. "Credit card companies take care of data that is greater than that."
New York is home to one of the largest recent immigrant populations in the U.S., and of course the Statue of Liberty off Manhattan has long been a welcoming symbol for newly-arrived foreign aliens.
