You may not have heard of Politwoops, but you can certainly understand why it exists.

The website, which is provided by The Sunlight Foundation, bills itself as “the only comprehensive collection of deleted tweets by U.S. politicians.” In an era where presidential candidates like Donald Trump and Hillary Clinton use Twitter to make and defend against off-color barbs, preservation seems key for a healthy democracy.

On June 3, Twitter pulled the plug on Politwoops, which was based on Twitter’s API, or application programming interface. (Less technically inclined readers should think of it like a guest key to the house of Twitter.) Twitter twtr and the Sunlight Foundation originally agreed to the arrangement in 2012, but Twitter quickly notified Sunlight that the site violated its terms of service. The two sides worked together for a time to preserve the project, Sunlight says, but Twitter in May had an unspecified “change of heart” and moved quickly to stop Sunlight’s access to its API.

“While we may no longer be able to publish deleted tweets,” a statement read on the Politwoops website, “we’re still working hard to advocate for more and better open data and to create tools that promote transparency and hold our government accountable.”

That has changed. Twitter announced on Thursday that it has a new agreement with the Sunlight and Open State foundations around Politwoops. It will allow tweets of public officials and presidential candidates to be recorded, stored, and published by Politwoops for the U.S. and internationally.

“We have a responsibility to continue to empower organizations that bring more transparency to public dialogue, such as Politwoops,” Twitter CEO Jack Dorsey said during a company conference in October. “We need to make sure we are serving all these organizations and developers in the best way, because that is what will make Twitter great.”

It’s unclear when the agreement will take effect; at press time, the Politwoops website still displayed its June eulogy. Still: Three cheers for a more transparent democracy.
