Carl Court/Getty Images(CNN) - Snapchat launched a political ads library as the mobile app becomes a campaign tool for 2020 candidates.
The new library, available as a downloadable spreadsheet on Snap's website, makes all political and issue-based ads on Snapchat publicly available -- for the first time.
Snap follows Facebook and Twitter in making political ads available in a public database.
In 2017, following Facebook's disclosure of election interference on its platform, Snap conducted an audit of its ad sales during the 2016 U.S. presidential election.
Issue ads include abortion, immigration, the environment, education, discrimination and guns, according to Snap's political ad policies.
