Magyar first came to prominence for his criticism of government politicians after the Katalin Novák presidential pardon scandal. In February 2024, Magyar released a voice recording of his wife that he had secretly made without his wife's knowledge or consent in which it was revealed that the president of Hungary, Katalin Novák, had granted a presidential pardon in April 2023 to Endre Kónya, the deputy director of a state-run children's home near Budapest. The deputy had coerced children into covering up sexual abuse by his superior, János Vásárhelyi, the home's director.[7] The scandal resulted in anti-government protests demanding that Novák resign; she did so on 10 February 2024.[8] The same day, Magyar's ex-wife Judit Varga, the former justice minister who had countersigned the pardon, also announced her resignation from the National Assembly and her role leading the Fidesz party list in the June 2024 European Parliament election.[8][5]

On 20 March 2024, Magyar testified for several hours at the Metropolitan Prosecutor's Office regarding the high-profile corruption case involving President of the Court Bailiffs György Schadl [hu][43] over bribes paid to former Secretary of State for Justice Pál Völner.[44] Shortly after his testimony, he announced to the press that he had proof in the form of audio recordings that Cabinet Minister Antal Rogán or his associates had manipulated documents in the case in order to hide evidence that would have incriminated Rogán. In a Facebook post a few days later, he promised to make the recordings public at 9 am on 26 March 2024, the date of his next appointment to testify and present the evidence to the prosecutors. He wrote that once this happened, Chief Prosecutor Péter Polt as well as the entire Orbán government would have no choice but to resign.[45] On 26 March, Magyar released the recording to the public. It contains a two-minute discussion between himself and his ex-wife Judit Varga about the Schadl-Völner corruption case. Varga's comments implicate Rogán in tampering with evidence by having his and/or his associates' names removed from documents associated with the case.[17] He has turned the recording over to prosecutors.[4]
