Free-agent quarterback Colin Kaepernick tweeted Monday he has spoken to rapper Meek Mill and will use his case as motivation to "continue to fight against the harsh sentencing practices" against people of color.
Mill received a prison sentence of two to four years earlier this month from a Philadelphia judge after he violated a term of his probation following a 2008 arrest.
Kaepernick's social activism extends well beyond pushing for change regarding mandatory sentencing procedures.
He began kneeling during the national anthem before NFL games last season in order to draw attention to police brutality against minority populations.
