Iowa Republican Congressmember Steve King sparked outrage Sunday after publishing a racist tweet in support of far-right Dutch politician Geert Wilders. Rep. King was retweeting a cartoon by the anti-immigrant group Voice of Europe depicting Wilders with a finger plugging a leak in a dike, labeled “Western Civilization,” holding back a toxic wave of Islam. The cartoon also depicts Muslim men with a sword and a suicide bomb vest. Rep. King’s retweet of the cartoon read, “Wilders understands that culture and demographics are our destiny. We can’t restore our civilization with somebody else’s babies.” The tweet drew praise from former Ku Klux Klan leader and Louisiana politician David Duke, who tweeted, “God Bless Steve King!” It was not Congressmember King’s first white supremacist comment. Last July, he told MSNBC that white Christians have contributed more to Western civilization than any other “subgroup.”
