Mariah Carey, wearing a T-shirt with the demand to "arrest the cops who killed Breonna Taylor," is reminding her fans to stay vigilant in the fight against racial injustice.

In a social media message posted on Sunday (Sept. 13), the back of the singer's shirt shows Taylor's face and the words "say her name." The singer also shared a picture in remembrance of Taylor, who was fatally shot by police in Louisville, Ky., in March.

"It’s been six months since #BreonnaTaylor, a frontline medical worker was killed by police in a ‘no-knock’ raid targeting the WRONG apartment," Carey posted, sharing a message from the Instagram account @wearepushblack.

"Medical workers like her save lives every day - but police violence claims Black lives at nearly the same pace.".
