As U.S. President Donald Trump spoke to African leaders at the United Nations on Wednesday, he made not one but two references to a country called Nambia.

“Nambia’s health system is increasingly self-sufficient,” Trump said approvingly at one point.

Unfortunately, there’s a problem — good health care or not, Nambia doesn’t exist. And so the U.S. president’s laudatory comments about a nonexistent country swiftly invited ridicule online, with many suggesting that Trump had created an entirely new nation by combining two existing ones — Zambia and Namibia.

A White House transcript of Trump’s comments corrected his error, making clear that the president had not intended to invent a new nation and had, in fact, been referring to the very real country of Namibia, which is in southern Africa.
