Twitter CEO Jack Dorsey hinted at the news at the social media giant's October Flight conference. Twitter had said preserving deleted tweets, even from elected officials, violated its agreement with developers.
"We have a responsibility to continue to empower organizations that bring more transparency to public dialogue, such as Politwoops," he said at the conference.
Twitter revoked developer API access for the project, a venture of The Sunlight Foundation and The Open State Foundation, in August 2015.
