President Trump's Muslim ban became the focus of general outrage from the moment it was signed into law in January 2017. Tens of thousands of Americans gathered at airports to protest the order. Lawyers were quick to file challenges and, within a day, obtained orders suspending implementation of the ban. Nobel laureates, university presidents, tech executives, and former secretaries of state condemned the Muslim ban. Even Dick Cheney declared that the ban "goes against everything we stand for." But, of course, this was not the first time that the United States targeted a particular group for exclusion.
