Mass rallies as Brazil political crisis deepens

Brazil faced a deepening political crisis and mass street protests Friday as opponents and backers of President Dilma Rousseff mobilized after lawmakers renewed efforts to drive her from office. Late Thursday, police in Brasilia fired tear gas and stun grenades to keep at bay angry protesters demanding her resignation.
