The claim comes from a personal social media account, not a verified journalist, researcher, or news organization. Serious accusations like human trafficking would normally be reported by major investigative bodies or credible media, especially if tied to someone as globally prominent in the political sphere as Volodymyr Zelensky. So far there is no supporting links to the DOJ's website corroborating this.
All major reports on Epstein-linked modeling operations has consistently focused on Jean-Luc Brunel, a French modeling agent who was arrested and charged in connection with Epstein's trafficking network, however there is no credible reporting on connections between Brunel to Zelensky or Olena Zelenska.
Publicly released Epstein files name many prominent individuals but Zelensky is not one of them, the modeling agency mentioned in the social media post, does relate to Brunel’s past work, but no verified documents connect it to Zelensky’s career in entertainment prior to politics. Zelensky’s pre political career was mostly in television and film production through his company Kvartal 95 which has little to no overlap with modelling agencies.
To conclude, there is no verified evidence that Zelensky is tied to Epstein, Brunel, or human trafficking in any way, and based on the current evidence available to the public, this rumor seems to be misinformation to hurt the image of the Ukranian President.
