His child, his son Flávio, who holds office as a legislator, called for a meeting of his supporters near his father's house to take place on Saturday night.
Flávio Bolsonaro wrote on online platforms on Friday: Do you plan to struggle for your nation, or observe everything from your mobile device there on your couch? I call on you to struggle with us."
