Thomas Roberts, who filled in after The Nation's Chris Hayes backed out of the guest-hosting slot, opened "Countdown" with a promise to address Olbermann's suspension and concluded with an explanation of the situation.
"Last night, MSNBC management became aware of three political contributions that Keith made to three different candidates last week," Roberts said. "The contributions are not permitted by NBC News without prior approval. In light of those facts, Keith has been suspended indefinitely."
We know all of you are looking forward to Keith's return, and so are we," Roberts added.
Roberts also made a lighter reference to the situation during a segment about Nancy Pelosi.
"It's always hard when you jump in the middle of some type of power contest," he said. "Trust me."
