Chris Christie has offered his solution to making sure immigrants don't overstay their time in the United States: track them like Fed Ex packages.

Speaking at a campaign event in Laconia, NH, Christie talked about how FedEx customers can track their packages at any point from the time it's sent to the time it's delivered. "So here’s what I’m going to do as president: I’m going to ask Fred Smith, the founder of FedEx, to come work for the government for three months," suggested the governor tp some laugh from the crowd.  "Just come for three months to Immigration and Customs Enforcement and show these people."

Christie says that visitors would then be notified when their time in the country is done. "Then we go get you, tap you on the shoulder and say ‘Excuse me, thanks for coming, time to go.' That would cut 40 percent of the problem we’ve developed over the last 30 years."

On Fox News Sunday, Christie told host Chris Wallace that his idea is "once again a situation where the private sector laps us in the government with the use of technology." He added that he is aware that people are not packages "so let’s not be ridiculous.”

Republican front runner Donald Trump has made immigration an issue in the campaign with his comments about Mexicans who come to this U.S. and his idea to build a wall along the southern border.

In an email, the Democrat National Committee criticized Christie's comments. "To compare immigrants and Americans to tracking a FedEx package is a new low of lows for the Republican field. The only tracking numbers that Christie should be concerned with is his poor job creation numbers and record nine credit downgrades.," said DNC spokeswoman Christina Freundlich. "The GOP should quit treating our nation's immigrant families as second class citizens -- or objects -- and join Democrats who support treating immigrants with respect and dignity."
