Republican Congressman Steve King said that America’s strength has nothing to do with diversity in a series of tweets Friday night.

King, a representative of Iowa, linked to an article from the Voice of Europe that quoted Hungarian Prime Minister Viktor Orban saying that all cultures should not be mixed because it’s “against common sense.”

“Diversity is not our strength,” King tweeted. “Assimilation has become a dirty word to the multiculturalist Left. Assimilation, not diversity, is our American strength.”

His list of controversial statements doesn’t stop there. Last year, King wondered what "subgroups" outside of white people contributed to civilization during an interview on MSNBC’s All In With Chris Hayes.
