Brazilian President Michel Temer remained defiant amid accusations he paid hush money to silence Eduardo Cunha, the former speaker of the lower house.

On Wednesday, Brazilian newspaper Globo reported two businessmen had sent prosecutors a recording of the president agreeing to payments to buy the silence of Cunha. Speaking on May 20, Temer said the audio recording was “manipulated.” He called on the Supreme Court to end an investigation into him and reiterated that he was in charge of Brazil despite calls for his resignation.

Cunha, who led the impeachment process against President Dilma Rousseff, was jailed after he was convicted of corruption, money laundering and tax evasion in March. The new accusations leveled against Temer sparked a new wave of protests across the country.
