Jérôme Bourbon is the head of the weekly oldest far-right newspaper Rivarol, founded in 1951 and still active today (Rivarol also has a Youtube channel). He is known for his Pétainism, antisemitism and negationism (mainly), which led to a dozen of convictions for racism, contestation of crime against humanity and incitment to hatred, among others. He is close to Jean-Marie Le Pen and to the rest of the French antisemitic/negationist scene.
