LOS ANGELES (

TheStreet

) -- Keith Olbermann will return to

MSNBC

on Tuesday after the anchor was suspended for contributing to the campaigns of three Democratic politicians.

"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,"

MSNBC

President Phil Griffin said in a statement late Sunday.

Olbermann acknowledged to

NBC

that he donated $2,400 each to the campaigns of Kentucky Senate candidate Jack Conway and Arizona Reps. Raul Grivalva and Gabrielle Giffords.

NBC News

prohibits its employees from working on, or donating to, political campaigns unless a special exception is granted by the news division president.

The

Politico

Web site first reported Olbermann's donations.
