Investigation of politicians sought in Brazil graft scandal

RIO DE JANEIRO: The inquiry into the biggest corruption scandal yet uncovered in Brazil entered an expansive new phase, as the attorney general formally requested the Supreme Court’s permission to open investigations against 54 people, most expected to be top political figures.

Previously, federal investigators had focused efforts on the companies but on Tuesday Attorney General Rodrigo Janot took aim at politicians, dealing what is seen as a blow to President Dilma Rousseff, herself a former chairwoman of Petrobras’ board.
