Nebraska Bird Partnership

Top officials of the Nebraska Chapter of the Sierra Club on Friday disavowed television advertisements targeting Nebraska's two U.S. senators for their vote on climate change legislation.

State Sen. Ken Haar of Lincoln, who has been on the local Sierra Club board, called the ads "stupid" and said he found them "personally offensive."  "Attacking is not the way we do business in the state of Nebraska," Haar said. "It reflects badly on Nebraska and makes it harder to work with our senators."
