Brazil's former president Jair Bolsonaro is set to be convicted of an attempted coup.
A live television broadcast on Thursday showed three of the five judges on the Supreme Federal Court voting to convict him.
The judges can still change their decisions until a verdict is pronounced on Friday, however.
In the five-member chamber, a majority of three votes is needed for conviction.
One judge voted for Bolsonaro's acquittal on Wednesday.
Bolsonaro is accused of plotting with allies to stage a coup against the government of his progressive successor Luiz Inácio Lula da Silva following his 2022 election defeat.
According to the prosecution, he had planned to impose a state of emergency and call new elections - but he was unable to win the support of the military leadership.
