While the bulk of the book was based on 20 hours of interviews Post staffers Marc Fisher and Michael Kranish conducted with Trump himself, the Trump Revealed Reporting Archive contains nearly 400 documents, including "thousands of pages of interview transcripts, court filings, financial reports, immigration records and other material." Although the paper scrubbed the documents for off-the-record interviews and other items it didn't have the rights to publish, the entire archive is searchable and downloadable. According to the paper, the archive is "meant as a resource for other journalists and a trove to explore for our many readers fascinated by original documents."
As Nieman Lab points out, amateur and professional sleuths alike are already finding fresh details that didn't make it into the biography itself, and more are sure to come as others dig into the documents. While the Post isn't the first to give outside reporters access to a vast reporting archive of sensitive materials, open sourcing the project is a refreshing counterpoint to a campaign that has frequently tried to paint the media as heavily biased and untrustworthy.
