If Trump’s current wife indeed worked while being on tourist visa then she broke immigration law.
If she broke immigration law, her citizenship can be revoked. That is as illegal act as the people crossing over border without visa to this country and working.
Since Trump and his supporters has made illegal immigration such a big issue this cycle, they should step up and and assure Americans that his wife is better than “illegal immigrants” in following immigration laws like he promised. But he won’t because there is probably something there that he doesn’t want you to see.
