George Floyd's brother says he still has nightmares about his murder as Congress reintroduces policing bill

George Floyd's family is still grieving, four years after he was murdered by a Minneapolis police officer. 

"(It's) absolutely hell," sister-in-law, Keeta Floyd tells CBS News. "They don't realize the things that are going on behind the scenes, for every life that has been lost since the death of George Floyd. It's extremely painful. It's a wound that never heals." 

Several members of the Floyd family joined members of the Congressional Black Caucus this week for the reintroduction of the George Floyd Justice in Policing Act. The measure, sponsored by Texas Rep. Sheila Jackson Lee, would enact stricter reforms to address police misconduct and strengthen accountability standards.
