Always one to stand up for social justice, J. Cole publicly voiced his support of Colin Kaepernick’s staunch role as an activist. On Wednesday night (Aug. 14), the KOD rapper took to Twitter to post a video of activists (including the late Michael Brown’s father) at war fighting against the police department’s unfair treatment of black people. The video also shows interludes of black men being assaulted by the authorities.

As a tribute to the work Kaepernick has done for the issue of racism and police brutality, Cole captioned the video, “Thank you @Kaepernick7 we ain’t forgot. @nfl let the man work.”
