Speaking publicly for the first time since his death, a tearful Ms Washington said Mr Floyd was a “good man”.
She said: “He slept the whole time that I went through labour, but when he heard her cry, he got up. I still have a picture of him waking up and getting his baby.
He loved her. He loved her so much.”
At least two people were killed and at least five police officers were shot on Monday night, violent episodes that came as angry protests continued across the US in the wake of the death of George Floyd.
The two deaths were in the Chicago suburb of Cicero, Illinois. An official confirmed Monday night that they were killed but did not offer more details.
