As President Joe Biden on Friday awarded the Medal of Honor to a 94-year-old Korean War veteran, he invited South Korea n President Moon Jae-in to speak -- the first time a foreign leader has participated in such a White House presentation.

"President Moon, it's a real honor to have you here participating in this ceremony today," Biden began, in his first time making the award. "The strength of the alliance between the United States, the Republic of Korea was born out of the courage, determination, sacrifice, and of the Korean troops fighting shoulder to shoulder with American troops. And having you here today is an important recognition of all that our nation has achieved together, both of them, in the decades since."
