Iowa Congressman Steve King has had enough with detractors who condemn the Republican Party for being full of “old white people,” and led a panel discussion into a shouting match by questioning whether any other “subgroup” of people have contributed more to civilization.

Sitting in on an MSNBC panel with host Chris Hayes at the GOP convention in Cleveland Monday evening, King reacted to a fellow panelist’s comment that he was “disappointed” that “old white people” still run the GOP platform.
