The Latest on the inauguration of Jair Bolsonaro as Brazilian president (all times local):

12:30 p.m.

Several of Brazil's new state governors have been sworn in ahead of the afternoon inauguration of President-elect Jair Bolsonaro.

Upon being sworn in, Sao Paulo Gov. Joao Doria promised to "rescue (the state's) passion for doing well." Doria was previously mayor of the city of Sao Paulo, Brazil's largest.

In Rio de Janeiro, Gov. Wilson Witzel reiterated campaign promises to crack down on crime, one of the state's biggest problems. He called drug traffickers "narco-terrorists," adding they would "be treated like terrorists."

Witzel, closely aligned with Bolsonaro, has floated ideas that include using sharp-shooters during police operations to shoot and kill drug traffickers.

Bolsonaro's inauguration is expected to begin around 3 p.m. local time (1700 GMT).

Former Brazilian army captain Jair Bolsonaro is taking office as president Tuesday promising to overhaul many aspects of life in Latin America's largest nation.

He is no longer the outsider mocked by fellow lawmakers for his far-right positions, constant use of expletives and even casual dressing.

Bolsonaro rose to power on an anti-corruption and pro-gun agenda that has energized Brazilian conservatives and hard-right supporters after four consecutive presidential election wins by the left-leaning Workers' Party.

He is the latest of several far-right leaders around the world who have come to power by riding waves of anger at the establishment and promises to ditch the status quo.

Brasilia will be under tight security, with 3,000 police patrolling the event. Military tanks, fighter jets and even anti-aircraft missiles will also be deployed.
