Colin Kaepernick and other high-profile athletes including LeBron James have taken to social media to voice their outrage over the death of a black Minnesota man who was pinned down by police.

George Floyd died Monday night while in Minneapolis police custody.

A bystander’s video showed an officer kneeling on the handcuffed Floyd’s neck, even after he pleaded that he could not breathe and stopped moving.

LeBron weighed in Tuesday night on Instagram with a post referencing Colin Kaepernick, the NFL quarterback who famously kneeled during the national anthem to protest police brutality and racial injustice.

James’ post includes a photo of the officer kneeling on Floyd’s neck alongside a photo of Kaepernick kneeling during the anthem.

Kaepernick also shared a version of the photo on his Instagram stories that had been tweeted by former NFL wide receiver Nathan Palmer. Formula One star Lewis Hamilton shared James’ post on his Instagram stories as well.
