Bolsonaro attacks courts, elections at Brazil rallies

The president additionally faces a Senate inquiry into his government's widely questioned handling of Covid-19

Coincidence that two days before, Brazil suspended the use of just over 12.1 million doses of the Sinovac coronavirus vaccine for 90 days after acknowledging that the vials containing the vaccines were filled on an unauthorized production base?

Why is he attacking the electoral system that got him elected?

So it worked for him but not anybody else after?
