U.S. Congressman: Whites have contributed more to Western civilization

U.S. Rep. Steve King of Iowa has set off a social media storm Monday after telling MSNBC's Chris Hayes that whites have contributed more to Western civilization than any other "subgroup."

King’s comments came during a panel discussion about diversity within the GOP and at the Republican National Convention in Cleveland this week — which one of the panelists, Esquire’s Charles Pierce, said was dominated “by loud, unhappy, dissatisfied white people.”

King responded by asking: “Where are these contributions that have been made by these other categories of people that you’re talking about? Where did any other subgroup of people contribute more to civilization?”
