The Brazilian government is targeting one of its biggest critics, journalist Glenn Greenwald, in a move that has been decried by observers as an intimidation tactic designed to stifle opposition to right-wing President Jair Bolsonaro.\u0026nbsp;The government\u0026#039;s finance ministry\u0026#039;s money laundering unit was asked by federal police to investigate Greenwald\u0026#039;s finances,\u0026nbsp;O Antagonista reported Tuesday. The right-wing Brazilian news site said that the investigation would focus on whether Greenwald paid for access to leaked records he used in reporting on the Bolsonaro government\u0026#039;s \u0022Operation Car Wash\u0022 sting.\u0026nbsp;\u0022If there is an investigation for doing journalism it is illegal and it is an attempt at intimidation,\u0022 University of Sao Paulo law professor\u0026nbsp;Pierpaolo Bottini told\u0026nbsp;The Guardian.This is a blatant attempt by Brazilian officials to intimidate—or worse—@ggreenwald for his reportinghttps://t.co/FwgDjSTEQm— jordan (@JordanUhl) July 4, 2019Attacks on Greenwald and his family, including husband David Miranda, a member of Brazil\u0026#039;s Congress, were criticized by U.N. and Organization of American States (OAS) Edison Lanza and David Kaye. In a joint press release, Lanza and Kaye called on Brazil \u0022to conduct an exhaustive, effective, and impartial investigation on the threats against the journalist and his family.\u0022\u0022The Special Rapporteurs remind the Brazilian State that it has an obligation to prevent, protect, investigate, and punish violence against journalists, particularly those who have been subjected to harassment and threats or other acts of violence,\u0022 the rapporteurs\u0026#039; statement said.Greenwald, co-founder of independent news organization\u0026nbsp;The Intercept, published in the online magazine\u0026#039;s Brazilian edition a number of investigations that use leaked documents to prove that the prosecution of former President Lula\u0026nbsp;da Silva for corruption was steered by now Justice Minister Sergio Moro. The reporting has impacted Brazil\u0026#039;s politics and thrown the Bolsonaro presidency into crisis.\u0026nbsp;Given the impact of the reporting, said José Guimarães, a congressman who is a member of da Silva\u0026#039;s Workers\u0026#039; Party, the investigation appears to be \u0022a brutal violation of press freedom.\u0022That point was echoed by Trevor Timm of\u0026nbsp;the Freedom of the Press Foundation. In a statement, Timm said that an investigation into Greenwald would be \u0022not only an outrageous attack on press freedom, but a gross abuse of power.\u0022\u0022Criminally investigating journalist Glenn Greenwald for reporting on corruption within the Bolsonaro government is a shocking violation of his rights as a reporter,\u0022 Timm said. \u0022Worse, the same person who is the primary subject of The Intercept\u0026#039;s reporting—Minister of Justice Sergio Moro—would also have ultimate authority over any Federal Police investigation.\u0022The fallout from Greenwald\u0026#039;s reporting is having a major affect on Brazilian politics. On Tuesday, Moro appeared in front of the Brazilian Congress to answer questions on \u0022Operation Car Wash\u0022 in a hearing that devolved at one point into near-violence.\u0026nbsp;After Congressman Braga laid out with unflinching clarity the corruption of Minister Moro as exposed by our reporting - see the above videos - the Congress members from Bolsonaro\u0026#039;s party reacted with the sobriety, dignity \u0026amp; eloquence for which they are internationally renowned: pic.twitter.com/k6OmZohnGN— Glenn Greenwald (@ggreenwald) July 4, 2019Greenwald, who spoke to the lower house of Brazil\u0026#039;s Congress about his reporting in June, was invited this week to testify in front of the Brazilian Senate. A date for that testimony has yet to be set.
