The show of support for Cosby took everyone by surprise that even a representative for West didn’t immediately respond to questions about the tweet.
Cosby has been charged with aggravated indecent assault in a 2004 incident at his suburban Philadelphia home in which a former Temple University women’s basketball assistant accuses him of drugging and molesting her.
Dozens of other women also have come forward to accuse Cosby of rape and unwanted sexual contact in incidents going back to the 1960s. Several of those women have sued Cosby for defamation. Cosby has denied wrongdoing.
In December, West debuted a song, “Facts,” which includes a line about the 78-year-old comedian.
“Do anybody feel bad for Bill Cosby? Did he forget names just like Steve Harvey?” West raps.
