A comic gag turned into a gaffe for Democratic presidential hopeful Hillary Clinton and New York Mayor Bill de Blasio, triggering a storm of social media comment accusing them of being insensitive to African-Americans.

Clinton on Saturday took the stage with de Blasio at the Inner Circle, an annual media roast of city and state politicians that traditionally ends with New York's mayor delivering a snarky rebuttal in the form of a rehearsed skit, often with the help of Broadway cast members.

This year Leslie Odom Jr., who is black and plays Aaron Burr in the hit Broadway show "Hamilton," participated in the skit in which Clinton teased de Blasio about his delay in endorsing her bid for the White House.
