retweetedStatus property
Users can amplify the broadcast of Tweets authored by other users by
retweeting. Retweets can be distinguished from typical Tweets by the
existence of a retweetedStatus attribute. This attribute contains a
representation of the original Tweet that was retweeted. Note that
retweets of retweets do not show representations of the intermediary
retweet, but only the original Tweet. (Users can also unretweet a retweet
they created by deleting their retweet.)
