Gov. Chris Christie is trying to keep himself in the top 10 for the next Republican presidential candidate debate as Donald Trump continues to surge in the polls and makes his second appearance in New Jersey in the past week.

Trump stopped by the Barclays golf tournament at the Plainfield County Club in Edison on Sunday and created a stir on the course as he posed for selfies with fans, including Eric LeGrand.

NJ.com reports that Trump turned down a special protection offered by Edison Police and PGA Tour security. He said he saw the cheering crowds as an "affirmation" that voters agree with the message on his cap to make America great again. "Not a heckler in the whole group out of thousands of people," Trump told NJ.com.

Two new polls continue to give Trump a solid lead in Iowa.  A Des Moines Register/Bloomberg Politics Iowa Poll released on Sunday gives Trump 23% percent ofth vote and Dr. Ben Carson receiving the highest favorability ranking. Chris Christie tied for 10th in the poll with 2 percent.

He is tied with Ohio governor John Kaisch for the 10th spot for CNN's debate on Sept. 16; a final ranking determining who will be on the main stage will be based on polls through September 10.

Trump appeared at a private event at the Long Branch home of his daughter Ivanka's in-laws, Seryl and Charles Kushner, according to the New York Times.

Christie will be a guest  on "The Tonight Show" on Monday night with Jimmy Fallon for the first time since April, when he was still playing coy about his presidential aspirations and took a big spoonful of "The Tonight Dough" Ben & Jerry's ice cream flavor. Victoria Justice, Gary Clark Jr. and Liev Screiber are also guests on the show.

Christie defended his suggestion made during a campaign stop in New Hampshire to use FedEx technology to track foreigners coming to the United States for a short period of time. On Fox News Sunday, Christie described his idea as “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.”

Christie said he'd hire FedEx founder Fred Smith for 3 months to get the idea off the ground.  “Just come for three months to Immigration and Customs Enforcement and show these people," said Christie.

Smith’s daughter Samantha is the Christie presidential campaign’s Communications Director. She previously worked for Google and John McCain’s 2008 presidential campaign.
