On Tuesday morning, 8,000 Starbucks coffee shops in America closed for a few hours for staff training on anti racial-bias. Common helped with the training by narrating a video for all staff to watch. The rapper/actor/producer paid a visit to Good Morning America to explain why he decided to take part in the training.

“Starbucks was just a microcosm of how black people have been dehumanized and I wanted to be a part of that conversation,” he said, adding how it’s important to “have a black man standing up and saying what we need.”

Common has previously partnered with Starbucks’ executive chairman, Howard Schultz after police killed Michael Brown in Missouri.

“After Michael Brown was killed, [Howard] was really trying to figure out how to get police and the communities together. And one of the things, one of the initiatives, I worked with him on was getting jobs for people in underserved communities,” Common said.
