New Jersey Gov. Chris Christie on Monday panned a proposal from fellow Republican presidential candidate Donald TrumpDonald TrumpRNC official declines to call Clinton a 'bigot' Beyond Trump and Hillary: What it really takes to transform election Leaked emails show Clinton, Dems split on linking Trump to GOP MORE to force Mexico to pay for a wall along its border with the U.S.
"This is not negotiation of a real estate deal, OK? This is international diplomacy, and it's different," Christie said, taking another shot at Trump, a celebrity real estate tycoon.
Trump has for months said that, if elected president, he would build a wall along America's southern border to deal with illegal immigration and force Mexico to pay for it, an idea at which Mexico has scoffed.
On Sunday, Trump listed the proposal first among his policy ideas for fighting illegal immigration, which he has made a centerpiece of his 2016 White House bid.
[T]he Mexican government has taken the United States to the cleaners. They are responsible for this problem, and they must help pay to clean it up," Trump's position paper reads.
In it, he proposes impounding undocumented workers' wages and raising fees on temporary visas to Mexican executives and officials, border crossing cards and on other visas.
Christie panned that plan on Monday, offering his own ideas for illegal immigration, including establishing fencing paid for the U.S. in certain places, especially urban areas, along the border, embedding FBI and federal drug agents with Border Patrol and using drones and other technology to monitor more difficult terrain.
Christie said the most important step, and one included in Trump's plan, is for the U.S. to employ the e-verify system to determine workers' eligibility.
"The fact is, these folks are coming over here to work. They're not coming to vote, they're coming to work. And if in fact they know they can't get jobs, then they're not going to come," Christie said on CNN.
