The bureaucratically nonchalant tone it used belied its significance. The tweet, at its core, purports to vest in the federal police and the federal government that oversees it the power to regulate, control, and outright censor political content on the internet that is assessed to be "false," and to "punish" those who disseminate it. The new power would cover both social media posts and entire websites devoted to politics.

"In the next few days, the Federal Police will begin activities in Brasília [the nation's capital] by a specially formed group to combat false news during the [upcoming 2018 presidential] election process," the official police tweet stated. It added: "The measures are intended to identify and punish the authors of 'fake news' for or against candidates." Top police officials told media outlets that their working group would include representatives of the judiciary's election branch and leading prosecutors, though one of the key judicial figures involved is the highly controversial right-wing Supreme Court judge, Gilmar Mendes, who has long blurred judicial authority with his political activism.
