Brazil’s Supreme Court has rejected a last-ditch effort by President Dilma Rousseff to avert a looming impeachment vote. Rousseff’s attorney general had sought to prevent lawmakers in Brazil’s lower house from voting this Sunday, amid reports her opponents have enough votes to advance the impeachment. The Senate would then vote on whether to put Rousseff on trial on accusations of breaking budget laws. Rousseff has accused her right-wing supporters of attempting a “coup.” Many of the lawmakers leading the impeachment charge face serious corruption and fraud charges of their own.
