Top prosecutor accuses president of corruption

The protest was sparked by Temer's statement on Thursday in which he vowed not to resign, insisting on his innocence. "In no moment did I authorize a payment to anyone for their silence", he said.

In a plea bargain by the same man who recorded Temer, released as part of the document dump by the Supreme Tribunal Federal, the president is accused of taking $1.5 million in bribes. Temer was caught on tape encouraging a prominent executive to pay a monthly fee to keep jailed former House Speaker Eduardo Cunha silent in the country's biggest-ever graft probe, sources said on Wednesday, confirming a report in newspaper O Globo.

"Brazil will not be derailed", he said during a speech in Brasilia, reiterating that he would not resign. According to O Globo newspaper, the police also has audio and video evidence that Temer's aide Rocha Loures negotiated bribes worth 500,000 reais (US$160,000) a week for 20 years in return for helping JBS overcome a problem with the fair-trade office.

One man, who is apparently Temer, complains Cunha could embarrass him.

The ongoing political turmoil in Brazil was triggered by the release of audio recordings, reportedly revealing that the president and his closest allies engaged in bribery schemes.

By late Friday, the real had clawed back 3 percent of its value and stocks were up almost 2 percent in the Ibovespa exchange.

The U.S. currency on Thursday gained 8.06 percent against the Brazilian real, which posted the highest losses since the country devalued its currency in 1999. Congress canceled its sessions, including suspending work on legislation that Temer's administration hopes will pull Latin America's largest economy out of its worst recession in decades.

The leaders of several other parties in Temer's coalition also planned to consult with their members Saturday in Brasilia.

The pressure built against Temer throughout the day.

"Michel Temer is like that boyfriend who doesn't know it's over", one Twitter user said.

The sprawling "Car Wash" probe that began three years ago has already put dozens of Brazil's top businessmen and politicians in prison. If the court made a decision to try Temer, he would be suspended from office for up to 180 days. Globo's report identified the men as Temer and Batista. Neves, who almost won the presidency in 2014 and planned to run again next year, has denied wrongdoing.

Wesley and Joesley Batista are two of the seven executives that signed a plea bargain with Brazil's Federal Public Prosecutor's Office in exchange for reduced sentences, according to the Financial Times. Globo did not say how it obtained the recording.

The testimony raises serious doubts about whether Temer, who replaced the impeached Rousseff previous year, can maintain his grip on the presidency amid the string of corruption scandals that has engulfed vast swaths of Brazil's political class and business elites. Temer's approval ratings are hovering around 10 percent.
