Federal prosecutors in Brazil on Tuesday charged the American journalist Glenn Greenwald with cybercrimes for his role in bringing to light cellphone messages that have embarrassed prosecutors and tarnished the image of an anticorruption task force.
In a criminal complaint made public on Tuesday, prosecutors in the capital, Brasília, accused Mr. Greenwald of being part of a “criminal organization” that hacked into the cellphones of several prosecutors and other public officials last year.
Mr. Greenwald, an ardent critic of Brazil’s far-right president, Jair Bolsonaro, is a deeply polarizing figure in Brazil, where his work is lionized by leftists and condemned as partisan and heavy handed by officials in the Bolsonaro administration.
The news organization Mr. Greenwald co-founded, The Intercept Brasil, published articles last year based on the leaked cellphone messages that raised questions about the integrity and the motives of key members of Brazil’s justice system.
The articles cast doubt on the impartiality of a former judge, Sérgio Moro, and of some of the prosecutors who worked on a corruption investigation that landed several powerful political and business figures in prison.
Among those charged in connection with the corruption investigation was a former president, Luiz Inácio Lula da Silva, a popular leftist whose conviction paved the way for the election of Mr. Bolsonaro. Mr. Moro was the judge who handled that case, and he is now Mr. Bolsonaro’s minister of justice.
