"Not only are you going to pay a lot more for food and meat, but a lot of the people who came here without permission or with limited permission that Trump wants to remove have American-born children," Johnston said. "So we're not only going to separate these families but your property taxes are going to go up because they're going to have to put millions of children into foster care, into orphanages, and we're going to have to bear the bill for that through our property taxes or sales taxes."

"In addition, when children grow up in circumstances like that, the likelihood we will have mental health and criminal problems in the future," he continued. "So the cost of this are way beyond the estimates that focus on just deporting people, and of course, Donald Trump said it will be bloody. And I don't see how it can be anything but that."

Trump has said his deportation operation would be modeled after former President Dwight Eisenhower's "Operation Wetback," which is the largest mass deportation program in U.S. history to date. As History.com reported, the operation was sloppy and costly and resulted in many U.S. citizens being rounded up in the mass deportation of approximately 1.3 million people. And earlier this year, Tom Homan, who was his former ICE chief, has promised that he would "run the biggest deportation force this country has ever seen."

"They ain’t seen s— yet. Wait until 2025," Homan said at the National Conservatism Conference in July.

Trump has previously promised to invoke the Insurrection Act of 1807 to juice his deportation operation, as it would allow the U.S. military to be deployed on U.S. soil to round up and detain undocumented immigrants across the country. Journalist Eleanor Clift warned that doing so would almost certainly result in human rights violations and would pose a massive risk to the economy.

""If such a plan were carried out, it would cause enormous disruption to communities throughout the country and increase the weight of the federal government in people's lives in a way that runs counter to a political party that supposedly prides itself on small government," Clift wrote in June.
