'Dad changed the world': George Floyd's 6-year-old daughter speaks out

George Floyd's 6-year-old daughter, Gianna, doesn't know how her father died, but she does know that everyone is talking about him.

"Dad changed the world," she said during a recent demonstration in Minneapolis.

Floyd died on Memorial Day after Derek Chauvin, a white Minneapolis police officer, pressed his knee against Floyd's neck while the handcuffed black man called out that he couldn't breathe. His death sparked outrage, leading to days of nationwide protests and murder charges against Chauvin.

Roxie Washington, Gianna's mother, said she couldn't bring herself to explain Floyd's death to his daughter.

"She said, 'I hear them. I hear them saying my daddy's name.' She doesn't know what happened. I told her that her dad died because he couldn't breathe," Washington said during an interview with "Good Morning America."
