Shaun King , a prominent black rights activist and writer, announced Thursday that he is co-founding a political action committee to help elect reform-minded prosecutors at the county and city levels.

The Real Justice PAC plans to spend upward of $1 million to support campaigns by progressives running for district attorney offices this year.

The efforts should benefit from Kings enormous social media following, as well as the expertise of several veterans of Vermont Sen. Bernie Sanders 2016 presidential campaign who are the groups other co-founders.

King views the initiative as an essential new stage in anti-racism and criminal justice reform movements in the era of President Donald Trump .

No position in America, no single individual has a bigger impact on the criminal justice system including police brutality, but the whole crisis of mass incarceration in general than your local district attorney, King said. They are the gatekeepers of Americas justice system.
