WASHINGTON (AP) — Steve King is a Republican congressman from Iowa who's a hard-liner on immigration with a penchant for making racially charged comments. Now he's facing heat for sharing a Twitter post by a Nazi sympathizer from Britain.

Mark Collett posted a screenshot of a Breitbart.com story citing opinion in Italy on immigration, where the new government recently refused to admit a vessel carrying African migrants. Collett is a self-described admirer of Adolf Hitler and is active in the digital "alt-right."

King retweeted the post and added: "'Europe is waking up ... Will America ... in time?"

King has stirred controversy with previous anti-immigrant comments such as a tweet last year that said, "We can't restore our civilization with somebody else's babies."

His office hasn't immediately responded to a message seeking comment.
