Trump assumes Harvard student asking about South Korea is Asian -- and pays for it

Republican presidential candidate Donald Trump was quickly set straight on Thursday when he questioned why an Asian-American Harvard student would be asking him about South Korea, the Huffington Post reported.

The student, identified as 20-year-old Joseph Choe, tried to push back on Trump's statement earlier this summer that South Korea doesn't "have to pay anything" for military support from the US.

"I just want to get the facts straight and say that --" Choe said before Trump cut him off to ask, "Are you from South Korea?"

"I'm not. I was born in Texas, raised in Colorado," the student replied, drawing some applause from the audience. "No matter where I'm from, I like to get my facts straight, and I wanted to tell you that that's not true. South Korea paid $861 million."

Choe's figure matches the one reported by The Diplomat earlier this year. However, instead of admitting his mistake, Trump called the figure "peanuts" and complained about US forces being stationed in not only South Korea, but Japan and Germany.

Choe later told NPR that he went to the event in Manchester, New Hampshire specifically to challenge the former reality star.

"I don't care who you are, whether you're the prime minister or Donald Trump, if you say something factually wrong or do something factually wrong, I'll call you out on it," he said. "[Trump] makes all these, like, weird accusations, whether it's toward Mexicans or women, or South Koreans; I just wanted to call him out on that."
