And, Giuliani says, even more Christie-sourced changes to Trump’s immigration stance will be forthcoming, like his call for tracking immigrant visas like Fedex packages, and using the E-Verify system to reduce illegal labor.

In an interview with NJ Advance Media on Thursday afternoon, Giuliani, a top adviser to the Republican presidential nominee, said Trump’s recent reversal on immigration policy came after his inner circle for several weeks suggested a more nuanced, practical and humane approach in dealing with the nation’s 11 million undocumented immigrants.

Asked if Christie was responsible for Trump’s softening approach to immigration, the former mayor responded: “The answer to that question is yes.”

The governor, Giuliani said, “is not the only one” counseling a more moderate stance on those who immigrated illegally, “but he is of great value to him.”
