When Bill Cosby spoke to NPR recently about his art collection, the interviewer raised the question of rape allegations against the comedian that have recently made headlines. Cosby didn't respond, the Guardian reports. "This question gives me no pleasure, Mr. Cosby, but there have been serious allegations raised about you in recent days," interviewer Scott Simon says. Cosby, who was interviewed with his wife, is quiet, NPR reports. "You're shaking your head no," Simon notes. "Do you have any response to those charges?"
Amid continued silence, Simon adds, "There are people who love you who might like to hear from you about this. I want to give you the chance." When Cosby stays quiet, Simon ends the interview. Cosby was supposed to appear on David Letterman's show this coming week, the Guardian notes, but the appearance has been canceled. A Cosby spokesman didn't give details, the AP reports. An appearance on The Queen Latifah Show set for Oct. 30 was postponed, the show says, after Cosby sought the move.
