Hi!,
As of today I am updating most of our Twitter streams to include extended_tweet and truncated fields. If the truncated is true, this means the Tweet is larger than 140 characters and it will be displayed in extended_tweet.full_text.

- French Politics
- French Media
- International News
- Climate Change
- COP21/COP22/COP23
- Risk Repository

"display_text_range": [

}
Happy text mining!
