MSNBC on Monday solidified its prime-time lineup by appointing Alex Wagner to fill Rachel Maddow's time slot four nights a week, Tuesday through Friday.
Wagner, who has worked at CBS News, as a co-host of Showtime's “The Circus” and as an editor at The Atlantic, is on her second stint at MSNBC. She rejoined MSNBC in February after hosting a show on the network a decade ago.
