Jadue has been accused by the Simon Wiesenthal Center of antisemitism, which placed him in its "Top Ten Worst Global 2020 Anti-Semitic Incidents". In response the following day, a group of academics and organizations, including the Argentinian branch of the small International Jewish Anti-Zionist Network, stated their support for Jadue, claiming that "It is inconceivable that critique towards the State of Israel, which has created a reality of apartheid in the occupied territory, be understood as a form of antisemitism". However, in June 2021, the press circulated a page from Jadue's yearbook featuring antisemitic humor, such as references to cleansing the city of Jews. After outcry from Chile's Jewish community, a conservative majority in the Chilean Chamber of Deputies approved a resolution, 79-47-20, calling on Jadue to denounce the Antisemitism of the document. Jadue rebuffed the call, saying "let's get serious."
