CNN anchor Jim Acosta says he's quitting after nearly two decades rather than accept a move from a morning time slot to a less visible midnight at the East Coast.

The network is moving Wolf Blitzer, a well-known CNN anchor, into his time slot, along with a co-anchor, Pamela Brown. Mr. Acosta’s show is third place in his time slot for total viewers, behind both MSNBC and Fox News, though he has outperformed his MSNBC competitor in the key demographic for advertisers.
