Flávio Bolsonaro wrote on social media on Friday: Do you plan to struggle for your nation, or see it all from your mobile device there on your settee? I call on you to struggle with us."
He said the vigil would be so backers could "pray for his well-being and for the reestablishment of democratic governance in our country."

The conspiracy was prevented because it couldn't obtain the backing of the army and air force commanders. The current president was took office without problem on 1 January 2023.
But a seven days after, on the eighth of January, many his backers attacked and damaged public facilities in the national capital, the capital city.
The security forces took action and around 1,500 people were taken into custody.
The justices found that the rioters had been incited by the former president whose scheme, they said, was for the national armed forces to intervene, bring back stability and reinstate his authority.
At the moment, Bolsonaro's lawyers called the over 27-year sentence "absurdly excessive.
He was also prohibited from running for public office until the year 2060 - eight years after the conclusion of his imprisonment.
