Mediapart Publishes Authenticated Messenger Messages Attributed to Jordan Bardella

Overview

• Mediapart published further material on Thursday saying it authenticated private Facebook Messenger conversations from 2013–2014 with a data extraction from Meta and certification by a huissier.
• The outlet released screenshots, a detailed method explanation and a so-called “boîte noire” that it says shows how sources, metadata and biographical details tie the exchanges to the account referenced as Jordan Bardella.
• Jordan Bardella denies authorship, calls the items "pseudo-preuves" and "montages grossiers," and has filed a defamation complaint while announcing a separate legal claim for falsification.
• The Rassemblement National has closed ranks behind Bardella, with senior figures calling the publication campaign interference, while other political leaders have urged restraint and said proof must be shown before judgment.
• The dispute is unresolved legally and politically and could influence the 2027 presidential campaign as courts and journalists test how platform data, huissier certification and media verification should be weighed.
