A model, he made the cover of the LGBT magazine Têtu[3] when he was 21 years old, then three years later, was on the cover of the German gentleman's magazine Gab.[4]
In 2014, he joined the National Front.[5] In 2017, Julien Odoul took over as head of the National Front Group in Bourgogne-Franche-Comté,[9] then joined the party's national office in 2018.[10] In 2019, he made comments during a council meeting along with a demand that a visitor take off her hijab. The visitor who was chaperoning a school trip was the mother to one of the children. Odoul's demand and remarks was rebuffed by council members with the council president, Marie-Guite Dufay, pointing out that neither French national law nor the regional council rules prohibited people from wearing veils during meetings.[11]
On campaign in the July 2024 French legislative elections for which he was the official RN spokesman, Odoul said that if the RN formed the government after the vote, they would ban the hijab in the public square.[12]
