Annals of Derp: President Don and Sec of State Rex had a great time

So Prime Minister Lee, prime minister of Singapore since 2004, and the son of Lee Kuan Yew who was prime minister from 1959 to 1990 and "senior minister" and "mentor minister" after that, is visiting the White House, and nobody in the State Department or the White House seems to have been able to find out what his name was (Hsien Loong is his given name, and "Loong" on its own is something his mother might call him) until after they'd humiliated themselves by publishing it in the wrong format everywhere in sight:

As you can see from the fourth item there, somebody made the same mistake last year when Lee visited Obama, but I don't think it was anybody official—the White House Historical Association, Time Magazine (in a Getty photo caption, not the article text), and the Daily Mail. And Singapore's independent Independent makes it clear that Obama did not do it himself.
