From this article, here’s a description of Trump’s comments at a meeting to prepare for a speech to Congress:
“Trump reminded them the crowds loved his rhetoric on immigrants along the campaign trail. Acting as if he were at a rally, he then read aloud a few made-up Hispanic names and described potential crimes they could have committed, such as rape or murder. Then, he said, the crowds would roar when the criminals were thrown out of the country — as they did when he highlighted crimes by illegal immigrants at his rallies, according to a person present for the exchange and another briefed on it later. Miller and Kushner laughed.”
