King retweets Nazi sympathizer

Aa controversal tweet this week from Iowa Congressman Steve King's is still dogging him.  According to the Huffington Post, the 4th District Republican said Thursday he doesn't know the person whose immigration-themed tweet he responded to on Tuesday.  Multiple media outlets have pointed out that Mark Collett, the British man King tweeted, is a Nazi sympathizer. King sent out another version of the tweet Thursday, but he didn't quote Collett--instead posting the original Breitbart News article about Italians and mass migration.
