Brazilian Senate leaders are stepping up support for the judiciary as it comes under fresh attack from President Jair Bolsonaro, who is gearing up for a re-election campaign by questioning the integrity of a voting system run by the courts.
The far-right president, who is trailing in the presidential race, has called the country's electronic voting machines vulnerable to fraud without providing evidence. That has raised concerns that he will not concede defeat if his leftist rival Luiz Inacio Lula da Silva prevails in this October's election.
