Donald Trump's immigration policy is "pretty much decided," but he still needs to work to "refine and decide" his specific plans on deportation, former New York City Mayor Rudy Giuliani, who has been advising the GOP presidential nominee, conceded on Monday.
"It will be pretty much the same thing as he always said," Giuliani told Fox News' "Fox & Friends" program, noting that the candidate plans to increase the numbers of Border Patrol and immigration agents, in hopes of both stopping people at the border and arresting and deporting more people in the country illegally.
"He's going to go after the most dangerous criminals first, then the less dangerous criminals second," he continued. "By the time we get there, then we'll see what our population is of non-criminal illegal immigrants."
However, Giuliani said he didn't know if some undocumented immigrants would receive a status short of legalization or citizenship that would allow them to remain in the United States.
"That's the debate," the former mayor said. "I don't know if you can decide that until you get down to that number."
Trump on Sunday tweeted that he will deliver a major speech on his immigration plans in Arizona on Wednesday. Last week, he said during a town-hall interview with Fox News' Sean Hannity that he'd be open to options on deportation and amnesty, but both he and his campaign insist that does not mean amnesty will be under consideration.
But his calls for a wall at the U.S.-Mexican border will remain, Giuliani said, and it will be like the wall built in Israel, which "Prime Minister [Benjamin] Netanyahu himself has told me was the most effective thing in securing their border that they've done in about 10 years."
The wall will be "technological" as well as physical, he continued, and will be able to "detect people five, six miles away" as well as people digging under the wall.
