A Brazilian senate committee has called representatives of Google, Facebook and Twitter to testify in an ongoing probe into the federal government handling of the COVID-19 pandemic. President Bolsonaro has posted several times treatments with little scientific grounding such as hydroxychloquine and invermectin as an alternative to proven methods such as social distancing and vaccines.
