Hillary involved in racially charged "joke"

“Thanks for the endorsement, Bill.” Ms Clinton said to cheers. “Took you long enough.” 
“Sorry, Hillary. I was running on CP time,” Mr de Blasio responded to groans from the audience. One member can be heard in the video yelling, “No.” 
“CP time” is shorthand for the phrase, “coloured people’s time,” which refers to the negative stereotype that black Americans are often running late. 
Mr Odom, who is black, responded in character: “I don’t like jokes like that, Bill. That’s not appropriate.”
