Sao Paulo police say they fired tear gas to stop vandalism after an "initially peaceful" demonstration Sunday against President MichelTemer.

Earlier in the day, people gathered on theCopacabanapromenade in Rio de Janeiro to demandTemer'sremoval and call for new elections.

Rousseffhas vowed to form a strong opposition againstTemer, who was her vice-president. She is appealing her impeachment to Brazil's Supreme Court, but legal experts say it is unlikely to succeed.

New elections could come ifTemerresigns before year end, is impeached himself or is disqualified for alleged campaign violations in 2014.
