(CNN) -- Prime-time host Keith Olbermann, who was suspended for violating the ethics policy of his employer, will be back on air Tuesday night, the president of MSNBC said Sunday.
Olbermann was suspended Friday after a news report by Politico revealed he had donated to three Democrats seeking federal office.
"After several days of deliberation and discussion, I have determined that suspending Keith through and including Monday night's program is an appropriate punishment for his violation of our policy. We look forward to having him back on the air Tuesday night," Phil Griffin, president of MSNBC said in a statement.
Olbermann gave $2,400 -- the maximum individual amount allowed -- to each of the campaigns of Kentucky Senate candidate Jack Conway, and Arizona Reps. Raul Grijalva and Gabrielle Giffords.
Conway lost his bid, while Grijalva and Giffords eked out wins.
The contributions violated an NBC policy that requires employees of the news organization to obtain permission ahead of any political donations or activities that could be deemed as a conflict of interest.
In what was apparently his first public comment since his suspension was announced, Olbermann wrote Sunday on his Twitter page: "Greetings From Exile! A quick, overwhelmed, stunned THANK YOU for support that feels like a global hug & obviously left me tweetless XO."
His comment was posted prior to Griffin's statement.
Olbermann's show, "Countdown," has been a staple of MSNBC's prime-time programming, and has some of the highest ratings on the network.
