Pelley, who has anchored Evening News since 2011, is reportedly being moved to 60 Minutes full-time. He currently splits time between Evening News and the Sunday newsmagazine, on which he has been a correspondent since 2004.
The move is reportedly due to a combination of underperforming ratings (Pelley's evening broadcast sits in third place behind Lester Holt on NBC and David Muir on ABC) and tension with CBS News president David Rhodes.
TVGuide.com has reached out to CBS representatives for confirmation. The network is expected to make an announcement Wednesday. Variety reports that CBS senior national correspondent Anthony Mason will be the interim anchor.
