Polish prosecutors are investigating far-right lawmaker Grzegorz Braun for denying the existence of gas chambers at Auschwitz, calling them 'fake'. His comments during a radio interview led to widespread condemnation, including from Auschwitz Museum Director Piotr Cywiński and Prime Minister Donald Tusk, who labeled Braun's remarks a 'disgrace'. The investigation is based on Polish law against Holocaust denial, which can result in prison time. Braun has a history of controversial actions, including previous incidents targeting Jewish and LGBTQ+ communities.
