That's what TPM is hearing, related to this Politico story:
MSNBC host Keith Olbermann made campaign contributions to two Arizona members of Congress and failed Kentucky Senate candidate Jack Conway ahead of Tuesday’s election a potential violation of NBC ethics policies.
Olbermann, who acknowledged the contributions in a statement to POLITICO, made the maximum legal donations of $2,400 apiece to Conway and to Arizona Reps. Raul Grijalva and Gabrielle Giffords. He donated to the Arizona pair on Oct. 28 the same day that Grijalva appeared as a guest on Olbermann’s “Countdown” show.
It now seems the suspension is "indefinite." And official:
"Anyone working for NBC News who takes part in civic or other outside activities may find that these activities jeopardize his or her standing as an impartial journalist because they may create the appearance of a conflict of interest. Such activities may include participation in or contributions to political campaigns or groups that espouse controversial positions. You should report any such potential conflicts in advance to, and obtain prior approval of, the president of NBC News or his designee."
Olbermann obtained no prior approval.
