MEXICO CITY (AP) — New Jersey Gov. Chris Christie on Thursday said he has no plans to lay out his positon on immigration reform until — and if — he decides to run for president.

Christie, who was in the middle of a three-day trade mission to Mexico, had conspicuously side-stepped the thorny issue on the first day of his trip, making no mention of legislation stalled in Congress or the flow of Central American children crossing into the United States illegally through Mexico.
