Brazil’s supreme court rejected President Dilma Rousseff’s bid to block an impeachment vote against her this weekend. The top court’s justices voted 8-2 against the Rousseff early Friday, dismissing her request to suspend Sunday’s lower house vote based on the claim that the voting procedures were flawed. The decision signals a blow to Rousseff, who has lost support from key lawmakers this week as the Chamber of Deputies inches toward the impeachment vote Sunday. Rousseff is accused of manipulating government finances to mask budget problems. If two-thirds of 513 house members approve her impeachment, the proceedings then head to the senate to vote for a possible trial.
