A Hillary Clinton joke about Bill de Blasio's support is drawing a racial backlash.

During a weekend press/political dinner that traditionally features skits, Clinton joked to de Blasio about the New York mayor's tardiness in supporting her, saying "thanks for the endorsement, Bill ... took you long enough."

“Sorry, Hillary,” de Blasio said. “I was running on C.P. time" — a comment that some believed referred to "Colored People time," drawing gasps from the crowd.

Leslie Odom Jr., an African-American actor in the hit Broadway play "Hamilton" who was also part of the skit, replied: "I don’t like jokes like that, Bill.”

To which Clinton jumped in with the kicker: “Cautious Politician time — I’ve been there."

Watch the video below — Clinton makes her entrance around the 8:20 mark.

The bit did not go over well. New York magazine called it "amazingly unfunny" and "terribly executed," while some Bernie Sanders supporters have called it downright racist.
