Dilma Rousseff was sworn-in here Thursday for a second four-year term as president of Brazil.
"I promise to uphold, defend and obey the constitution, to observe the laws, to promote the general welfare of the Brazilian people, to maintain the unity, integrity and independence of Brazil," the country's first woman president said during the solemn ceremony in Congress.
The 67-year-old Rousseff pronounced those words for the first time in January 2011, when she succeeded her political mentor, two-term president Luiz Inacio Lula da Silva.
