From President Donald Trump's December 15 address to the FBI National Academy:
PRESIDENT DONALD TRUMP: As president, my greatest duty is to protect our nation and to protect our people. As we have witnessed recently, America faces grave threats. Terrorists have struck in the streets and subways of New York City twice in a few months. Both terrorists came to our country through the dysfunctional immigration system that we are correcting, and rapidly. And one came through chain migration. Chain migration. The other, visa lottery. They have a lottery. You pick people. You think the country is giving us their best people? No. What kind of a system is that? They come in by a lottery. They give us their worst people, they put them in a bin, but in his hand when he is picking them is really the worst of the worst. “Congratulations, you are going to the United States,” OK. What a system, lottery system. We are calling for Congress to end chain migration and to end the visa lottery system and replace it with a merit-based system of immigration.
