A Brazilian Supreme Court judge on Tuesday ordered top executives from Google, Meta and Spotify to appear before the country’s federal police to testify about a public campaign against pending legislation that takes aim at so-called fake news.

Google on Monday ramped up its efforts to stop the bill, which seeks to clamp down on the spread of online disinformation and hate speech and was on the cusp of a potential Tuesday evening vote in Brazil’s lower house of congress. The company posted a message to its landing page warning Brazilian users that the legislation “could make your internet worse.”
