Bob Edwards, back in D.C. in a break from his book tour, said NPR bosses didn’t give him the option of co-hosting the show before they reassigned him [RealAudio file.]. “I was never asked to be a co-host, I was never told I would have a co-host. None of that came up,” Edwards said on Diane Rehm’s talk show May 21. Program chief Jay Kernis has said NPR wanted two hosts for the show that Edwards hosted alone. He said he will remain at NPR “for the time being,” but owes it to himself and his family to review “attractive options” offered by others.
