A man who spent nearly two decades in prison after being wrongly convicted of murder has dubbed Kamala Harris an 'opportunist' who should recognize she has 'ruined a few lives' during her time as a prosecutor. Harris, 55, who was added to the Democratic ticket last week, served as the San Francisco District Attorney between 2003 and 2010 before becoming California's Attorney General. Now her record in both roles is coming under scrutiny as she prepares to battle for the White House alongside Joe Biden.
