Aug. 7 (UPI) -- Gustavo Petro, a former member of the M-19 guerrilla organization, was sworn in as Colombia's president on Sunday afternoon with the country's first Black vice president, Francia Márquez.
Petro, 62, became Colombia's first leftist president after defeating candidates from conservative parties during the June election and has promised to fight economic and social inequality in a country where 40% of households live on less than $100 a month.
