I think this is it: "In late January, Donald Trump did something that would have sunk almost any other presidential campaign: He retweeted an anonymous Nazi sympathizer and white supremacist who goes by the not-so-subtle handle @WhiteGenocideTM. Trump neither explained nor apologized for the retweet and then, three weeks later, he did it again. This subsequent retweet was quickly deleted, but just two days later Trump retweeted a different user named @EustaceFash, whose Twitter header image at the time also included the term “white genocide.”

Now, this is from  Fortune. One could argue they are left wing, but this is a quote. Unless it has been edited, one cannot bias a true statement except in the interpretation. The source without question.
