LOS ANGELES (AP) — Comedian Don Rickles has died at age 90.

Paul Shefrin, his longtime publicist and friend, said Rickles died today (April 6) of kidney failure at his Los Angeles home.

For more than half a century, "Mr. Warmth" headlined casinos and nightclubs from Las Vegas to Atlantic City, N.J., and appeared often on late-night TV talk shows.
