A newly published poll seems to test the limits of political unpopularity in Brazil.
The survey by the Datafolha polling institute shows just 7 percent of those questioned approved of President Michel Temer's administration.
That's down from 9 percent in April.
Temer's rating has now plummeted to the lowest level for an office holder since Jose Sarney fell to 5 percent in 1989.
Sixty-nine percent of those polled for the survey commissioned by the Folha de Sao Paulo newspaper said Temer's performance has been either bad or terrible.
Another 23 percent called it average.
The poll published surveyed 2,771 voters between June 21 and June 23. The margin of error is 2 percentage points.
Temer is due to find out next week if the Brazil's top prosecutor will lodge formal charges against him over allegations that he took bribes in exchange for political favors doled out to meatpacker JBS SA.
The Brazilian President has repeatedly denied any wrongdoing.
Two weeks ago, Temer was acquitted of financial irregularities in the 2014 election campaign when he ran as vice president.
That ruling came just a day before he was forced to deny further damaging allegations, when an article in Veja magazine claimed that the country's secret security service, known as Abin, had spied on the justice overseeing the Operation Car Wash investigation.
Dozens of politicians are being probed over bribery claims linked to the state-run oil company Petrobras.
