Ashley Yates, also known on Twitter as Brown Blaze, is a key organizer in the #BlackLivesMatter movement.  She was at the center of the Ferguson protests after the police killing of unarmed teenager Michael Brown and continues to organize around issues of police brutality and institutional racism.  She was among the protesters who made headlines by interrupting presidential candidates Bernie Sanders and Martin O’Malley at Netroots Nation in late 2015.
