Brazil’s interim government came under fire on Monday, as a secret recording emerged of Juca discussing an alleged agreement to push for President Dilma Rousseff’s impeachment to stall a massive corruption probe that has engulfed much of the South American nation’s political class.

A leaked recording of a phone conversation is adding to pressure on Brazil's acting President Michel Temer.

The recording made public Monday shows one of his closest advisers telling a company president that impeaching President Dilma Rousseff would be the best way to stall the corruption probe at oil giant Petrobras that has ensnared many top politicians.

Planning Minister Romero Juca has confirmed the conversation that was revealed by the Folha de S.Paulo newspaper, saying it occurred early this year. He denies that making Temer president was intended to stop the investigation.

Brazil's Senate voted to impeach Rousseff on May 12 and Temer took over temporarily.

Juca himself is under investigation for alleged corruption. He's rejected calls to resign by members of Rousseff's Worker's Party and some of Temer's allies.
