Where to begin? How about with a simple observation: The president of the United States is a racist. And another: The United States has a long and ugly history of excluding immigrants based on race or national origin. Mr. Trump seems determined to undo efforts taken by presidents of both parties in recent decades to overcome that history.

Mr. Trump denied making the remarks on Friday, but Senator Richard Durbin, Democrat of Illinois, who attended the meeting, said the president did in fact say these “hate-filled things, and he said them repeatedly.”

Of course he did. Remember, Mr. Trump is not just racist, ignorant, incompetent and undignified. He’s also a liar.

Even the president’s most sycophantic defenders didn’t bother denying the reports. Instead they justified them. Places like Haiti really are terrible, they reminded us. Never mind that many native-born Americans are descended from immigrants who fled countries (including Norway in the second half of the 19th century) that were considered hellholes at the time.
