Brazil's Rousseff under pressure but impeachment seen unlikely

She does not face an immediate risk of impeachment, leading opponents told Reuters, but that could change if prosecutors find evidence that Rousseff knew of or benefited from the massive graft scheme.
Prosecutors say executives at Petroleo Brasileiro SA , as Petrobras is formally known, conspired with contractors to skim billions of dollars for themselves and political parties when Rousseff was the company's chairwoman from 2003 to 2010.
The scheme continued after she became Brazil's president in 2011.

However, a steady stream of arrests and new revelations about the misappropriated money, as well as a recent sharp downturn in Brazil's economy, appear to have emboldened Rousseff's opponents in Congress and elsewhere.
In a poll published over the weekend that showed Rousseff's approval ratings sinking to an all-time low, 77 percent of respondents said they believed she knew about the corruption at Petrobras.
