Donald Trump tweeted this image earlier today. He deleted it approximately 40 minutes later.
Why was the picture problematic? The images are not of this individual's parents, but are Fred and Rosemary West, English serial killers who murdered at least 11 girls over a period of 30 years.
Quite a lot of people noticed his tweet.
The tweet originated from @feckhead, who describes himself on his Twitter profile as a "failed comedian".
