Trump accidentally slams Don Jr. in magazine profile of Ivanka

President Donald Trump damned his namesake son with faint praise in a lengthy profile on his eldest daughter.

The president spent 20 minutes on the phone with The Atlantic's Elaina Plott bragging about Ivanka Trump, whom, he revealed, he wanted to place at the United Nations or World Bank because she's "good with numbers" and "calm," which he attributed to her genetics.

Trump told the reporter he was proud of all five of his children, although it was clear he was most reverent of the 37-year-old Ivanka -- a White House senior adviser he sometimes calls "baby" in official meetings.

“Barron is young, but he’s got wonderful potential,” Trump said. “And Tiffany’s doing extremely well. Don is, uh, he’s enjoying politics; actually, it’s very good."

"And Eric is running the business along with Don, and also very much into politics," he added. "I mean, the children — the children have been very, very good.”

Trump sees Ivanka as his heir apparent, the reporter concluded, and seemed to think she could one day take over the job he unexpectedly won.

“If she ever wanted to run for president,” he said, “I think she’d be very, very hard to beat.”

Donald Trump Jr. has floated the possibility of entering politics, and he's popular at his father's campaign rallies, but the president said he only considered Ivanka for an administration post.

"She went into the whole helping-people-with-jobs," he said, "and I wasn’t sure that was going to be the best use of her time, but I didn’t know how successful she’d be. She’s created millions of jobs, and I had no idea she’d be that successful.”

That claim about millions of jobs, the reporter noted, was not true.
