Twitter is applying labels to tweets that, by its standards, are prematurely calling election results for either candidate.
“Official sources may not have called the race when this was Tweeted,” the label reads.
The social network previously explained its new rules in a blog post: "To determine the results of an election in the US, we require either an announcement from state election officials, or a public projection from at least two authoritative, national news outlets that make independent election calls. Tweets which include premature claims will be labeled and direct people to our official US election page."
With this type of label, Twitter is not indicating the tweet contains potential misinformation. Instead, it is meant to give people reading the tweet context and help them parse projections as the night goes on.
When people try to share the tweet, they are first prompted to "find out more" and are directed to Twitter's official election page. Labeled tweets can only be quote tweeted, not retweeted. Users can still reply or like a labeled tweet. (Quote tweets append a user's commentary to the original tweet.)
Here's one of the first tweets that Twitter labeled (CNN would call Florida for President Trump hours later):
