In this presidential cycle, Mckesson has met with both Hillary Clinton and Bernie Sanders as part of a broader effort to lobby for the end of "broken windows" policing and an increase in local oversight of police departments.
DeRay Mckesson's late entry into the mayoral race is filled with uncertainty. It's still unclear just how organized his campaign is, and how much of a chance he stands in a race that already has a big field of candidates just on the Democratic side.
But Mckesson's entrance into the race is a big deal: It's the first time a major Black Lives Matter activist has directly entered the political arena as a potentially serious candidate.
Mckesson was on Fortune’s 50 Greatest Leaders list last year for his involvement in the Black Lives Matter protests. The activist participated in protests following the death of Freddie Gray. As a member of Campaign Zero, a movement to end police brutality, Mckesson has met with White House officials and politicians to discuss civil rights.
