"The purpose of the decision is also to find out whether there was payment for transportation and per diems for those who participated in the demonstrations and whether there was content for an early election campaign," the court said.

"The purpose of the decision is also to find out whether there was payment for transportation and per diems for those who participated in the demonstrations and whether there was content for an early election campaign," the court said. The probe comes at a difficult time for Bolsonaro, a far-right former army captain who has overseen the world"s second-deadliest coronavirus outbreak while grappling with rising inflation and a weak economy. He and his supporters are angry at federal courts for authorizing investigations into him and his allies based on accusations that they had attacked the country"s democratic institutions. Bolsonaro has accused the court of intimidation and also questioned the validity of next year"s election, citing unfounded cases of voter fraud. At the rallies last week, his supporters repeated their accusations against the Supreme Court, while Bolsonaro said he would no longer follow rulings by Justice Alexandre De Moraes, who has led some of the most sensitive probes against the president and his supporters. Bolsonaro later sought to defuse tensions, saying in a note that he never intended to attack any branch of the government.
