“We love to boast that we are a nation of immigrants — and we are. But there's a different sense of America among those who trace their bloodlines back through generations of sacrifice.”

State of the Union address http://millercenter.org/president/clinton/speeches/speech-3440 (24 January 1995)
1990s
Context: All Americans, not only in the States most heavily affected but in every place in this country, are rightly disturbed by the large numbers of illegal aliens entering our country. The jobs they hold might otherwise be held by citizens or legal immigrants. The public service they use impose burdens on our taxpayers. That's why our administration has moved aggressively to secure our borders more by hiring a record number of new border guards, by deporting twice as many criminal aliens as ever before, by cracking down on illegal hiring, by barring welfare benefits to illegal aliens. In the budget I will present to you, we will try to do more to speed the deportation of illegal aliens who are arrested for crimes, to better identify illegal aliens in the workplace as recommended by the commission headed by former Congresswoman Barbara Jordan. We are a nation of immigrants. But we are also a nation of laws. It is wrong and ultimately self-defeating for a nation of immigrants to permit the kind of abuse of our immigration laws we have seen in recent years, and we must do more to stop it.

2015, Naturalization Ceremony speech (December 2015)
Context: We celebrate this history, this heritage, as an immigrant nation. And we are strong enough to acknowledge, as painful as it may be, that we haven’t always lived up to our own ideals. We haven’t always lived up to these documents. [... ] We succumbed to fear. We betrayed not only our fellow Americans, but our deepest values. We betrayed these documents. It’s happened before. And the biggest irony of course was -- is that those who betrayed these values were themselves the children of immigrants. How quickly we forget. One generation passes, two generation passes, and suddenly we don’t remember where we came from. And we suggest that somehow there is “us” and there is “them,” not remembering we used to be “them.”
