Former MSNBC host Keith Olbermann, who once occupied the network’s 8 p.m. ET slot, wished Chris Hayes luck on Thursday as the weekend cable news host moves to primetime. But not before taking a swing at the network’s volatile 8 p.m. time slot.
So, four different 8 PM shows in 27 months. Good luck out there @chrislhayes
