The attorney general of Minnesota is the lead prosecutor in the trial for murder of George Floyd who died in May last year. His death became front page news after a video showed a white police officer kneeling on his neck for nearly nine minutes. It sparked massive civil unrest and forced a wider debate about law enforcement and racial inequality. Keith Ellison's role in the trial which started this week will be closely watched. He was born in Detroit in 1963, one of five brothers to parents with high expectations and a strong sense of social justice. As a young law student he became involved in community activism, a path which led to his election to Congress in 2006, the first muslim to achieve that. Becky Milligan talks to his family and friends.
