The Associated Press has added a new entry on retweeting to its social media guidelines. Staffers are reminded to keep their opinions to themselves.

Retweets, like tweets, should not be written in a way that looks like you’re expressing a personal opinion on the issues of the day.
Disclaimers — like “retweets do not constitute endorsements” — do not protect AP staffers if they violate these guidelines. —AP issues staff guidelines on retweets, no ‘personal opinions’ allowed or implied
