ICYMI: Wednesday was the First Lady's birthday. Not Ivanka, the other one. So Donald Trump, of course, celebrated by wishing his wife (Melania) "happy birthday" on Twitter. And although it was very sweet of his staff to remind him of his wife's birthday, there's one problem: the birthday tweet contains a major factual error (aside from the word "happy").
Can you spot it?
Look very closely at the flag.
