Washington (CNN) The immigration lawyer representing first lady Melania Trump's parents pushed back against President Donald Trump's hardline stance on a category of family visa that paved the way for his in-laws' citizenship, calling the President's rhetoric "unconscionable."

"It's unconscionable to scare people into believing that," the attorney, Michael Wildes, said Friday in an interview on CNN's "Erin Burnett OutFront" after listening to a replay of Trump calling so-called chain migration "a disaster for this country."

"This whole notion of chain migration actually is a beautiful bedrock of immigration law and policy called family reunification," Wildes said, noting he was speaking about his personal beliefs and not on behalf of the first lady or her family as their lawyer.

"Imagine this, people will work harder and love more, and do more for America knowing that their loved ones, their immediate relatives, their parents, their children ... to say you can bring one relative and not another relative ... I can understand that some of them may be in jeopardy, and you may want to retool an antiquated immigration system. It looks weird to have a lottery system. But chain migration?
