New York (CNN Business) The League of Conservation Voters is cutting ties with an upcoming forum on climate change after the co-host for the event, The New Republic, published an "offensive" article about Democratic presidential candidate Pete Buttigieg.

Gene Karpinski, LCV's president, said in a statement Saturday that the piece about Buttigieg and The New Republic's decision to run it "are inconsistent with our values."

LCV, a high-profile environmental group that has spent years lobbying for tougher action on climate change, had signed on to co-host a 240-minute discussion about the issue for the current presidential candidates at a forum in September.

"LCV is withdrawing our participation in the presidential primary candidate climate forum previously announced in New York City on September 23," statement says.

Media site Gizmodo, a co-host of the event, said the New Republic has also pulled out as a host.
