Not really. He has never had any real legislative power to back him. The biggest scandal surrounding his party was paying off congressmen and heads of parties in order for them to vote for welfare policies. These policies never would've been voted in if that was not the case. A lot of parties gatekeep votes for important legislation until they get handouts.

Ironically (or not at all) the man who individually received the most money from that scheme is the head of Flavio Bolsonaro's party, and the party who received the most payoff as a whole was Jair Bolsonaro's party at the time.

Politics in Brazil require a great deal of consensus, obscure dealmaking and corruption.
