WASHINGTON — Carl Kasell, a signature voice of NPR News for decades, is stepping down from the comedy news quiz show “Wait, Wait … Don’t Tell Me!” and retiring from the network this spring.

Kasell has been a recognizable voice on NPR for decades. He was a newscaster for 30 years on “Morning Edition” until 2009. His radio career spans half a century, starting as a morning deejay and newscaster at WGBR-AM in Goldsboro, N.C.

NPR announced Kasell’s retirement Tuesday.

Kasell says his time on “Wait, Wait” has been his favorite at NPR.
