Murphy wasn't the only one to note Pence had condemned NFL players for kneeling in protest during the national anthem.
During the weekend, my tour guide Cindy told me she was upset with South Korean President Moon Jae-in for welcoming such a large contingent from the North, including Kim's sister.
At Friday's Olympic opening ceremony, athletes from the two nations wore the same white jackets and marched together under a united Korean flag.
"Having these red communists in the heart of Seoul is a humiliation!" one demonstrator yelled near the theater as dozens waved signs and banners condemning Moon and Kim Jong Un.

South Korean activists burned the North's flag yesterday near a theatre where North Korean leader Kim Jong Un's sister and the South's President watched a North Korean musical display in a culmination of their Olympic rapprochement.
But there was no mention of the North Korean nuclear issue or joint U.S.
Some 140 members of Pyong-yang's Samjiyon Orchestra gave a concert in Seoul as part of a deal in which the North sent hundreds of athletes, cheerleaders and others to the Pyeongchang Winter Games.
Blue House spokesman Kim Eui-kyeom cited Moon as replying: "Let's create the environment for that to be able to happen".
