Despite this defiant stance, the impact of this political crisis on Brazil was felt immediately.
Brazil's President Michel Temer is teetering in the wake of corruption allegations, with many asking whether he can survive. Brazil's political crisis deepened sharply on Thursday with corruption allegations that threatened to topple the presi.
His address was followed shortly after by street demonstrations in Rio de Janeiro, São Paulo, Brasilia and other cities demanding his resignation. Demonstrations calling for Temer's resignation are set to take place on Sunday, AFP reports. His legal team is questioning the evidence against him.
By midday Thursday, three requests by lawmakers for the impeachment of Temer had been filed.
Temer has denied the charges and decried the report as a "conspiracy" against him.
Two big newspapers, Estadao and Folha, first raised the question of whether the audio had been tampered with in articles on Saturday that quoted forensic experts.
Temer spoke in only his second public appearance since Wednesday's (May 17) revelation of the audio recording, and the opening on Friday (May 19) by the Supreme Court of a formal probe.
They are accused of having discussed hush money for a witness in the exchange. Representatives of Temer and Rousseff had no immediate comment.
Despite all the calls for his head, the veteran center-right politician - who took over past year after the impeachment of leftist president Dilma Rousseff - came out swinging. That leaves impeachment proceedings as the most likely avenue to remove Temer from power, just like a year ago when Rousseff was stripped of her office and Temer, her vice president, automatically got the top job.

Anti-Temer demonstrations have also been held in San Paolo and the country's capital, Brasília, where demonstrators gathered in front of the parliament building.
In the documents released Friday, Batista also said his company paid Temer about $1.5 million from 2010 to 2017. The company generally wields enormous influence among Brazilians because of its popular soap operas and media dominance.
At the occasion Janot issued an order that cited other politicians who should be investigated "with the exception of the current president, Michel Temer" who "has temporary immunity to penal prosecution".
Janot accused Temer and Sen. Aecio Neves have tried to derail the "Car Wash" probe via legislative means and by influencing police investigators.
Temer came with the promises of "new era", while the opposition had been claiming that Temer was involved in far more corruption, controversy, instability, and shame than his predecessor.
The scandal has engulfed Brazilian politics, with a third of Mr Temer's cabinet under investigation for alleged corruption.
At least eight pieces of proposed legislation to impeach Temer have been submitted in Congress, and a steady stream of people from many walks of life are continue to call for him to step down.
The pressure built against Temer throughout the day.
"If Temer doesn't fall, he will lead a walking dead administration", said Claudio Couto, a political science professor at Fundacao Getulio Vargas, a Sao Paulo-based university and think tank.
Retired teacher Adilson dos Santos was equally unimpressed with Temer's words.
