President Trump doesn’t try to hide that he thinks his daughter Ivanka Trump, whom he refers to as “baby” during official meetings, is his most “unique” child.

During an interview with The Atlantic for a new in-depth piece on Ivanka Trump’s transition from New York high society to “playing government” in the White House — as former Chief of Staff John Kelly referred to her role in the administration — Trump praised Ivanka Trump as his “heir apparent,” in The Atlantic’s words.

Trump told The Atlantic he was proud of all of his children, but heaped praise on the first daughter, who would be “very, very hard to beat” if she ever decided to run for president. He also revisited a notion he’s floated in the past: that she would’ve been “incredible” as the ambassador to the United Nations.

“If I did, they’d say nepotism, when it would’ve had nothing to do with nepotism. But she would’ve been incredible,” he said, adding that he’d considered her for the World Bank, too, because she’s “very good with numbers.”

“She’s got a great calmness … I’ve seen her under tremendous stress and pressure,” he said. “She reacts very well—that’s usually a genetic thing, but it’s one of those things, nevertheless. … She’s got a tremendous presence when she walks into the room.”
