This article is based on a newspaper story from April of this year. The Clinton campaign is hoping that we will have forgotten this by now.
The Washington Post posted the following on April 26, 2016:
Mr. Quigg, the leader of the Klan’s California chapter, announced last month that he had abandoned supporting Republican presidential front-runner Donald Trump in lieu of backing his likely Democratic opponent. The Klansman claims that members have raised more than $20,000 for Mrs. Clinton and have donated it anonymously to her campaign.
Obviously her campaign spokesman rejected the endorsement. Hillary Clinton released an ad today accusing Donald Trump of endorsing the views of the KKK. I guess she’s not interested in giving the Trump campaign the benefit of the doubt that she claimed for her campaign. She is obviously not interested in waging a campaign on facts–those are not on her side.
