As we mentioned, the lower house is expected to vote on impeachment today. A two-thirds majority is required for the vote to go forward to the Senate. If that happens, a simple majority is required to suspend Rousseff for up to 180 days, while she is put on trial.
Vice President Michel Temer would step in. Rousseff will be permanently removed from office if two-thirds of the Senate vote in favor. Rousseff is accused of manipulating government accounts ahead of her re-election in 2014. She denies the charges.
