The man in line to become Brazil's next head of state if President Dilma Rousseff is impeached says he won't run for the presidency in 2018 when Rousseff's term comes to an end.

Vice President Michel Temer also said he would support a proposal to end presidential re-elections in Brazil.

Presidents are elected to four-year terms and can be re-elected to a second consecutive term. A third term is allowed if they take a four-year break after the second.

Temer made his remarks Thursday in an interview with the SBT television network. Local media said it was an attempt to attract the support of the country's largest opposition party, the Brazilian Social Democracy Party.

On Friday, Judge Sergio Moro, who is heading the investigation into the sprawling corruption scheme involving state-run oil company Petrobras accepted charges filed by prosecutors against Joao Santana, the political marketing expert who helped Rousseff win two elections.

Prosecutors have charged Santana and his wife, Monica Moura, with corruption and money laundering. They allege the couple received $3 million in illicit funds from offshore companies controlled by the Odebrecht construction company, which is under investigation for its involvement in the Petrobras bribery scheme.

The acceptance of the charges by the judge means Santana and Moura are now defendants in the investigation.
