The controversy over Brave New Films' film accusing the Koch brothers of bankrolling the 2009 Wake County school board elections is heating up tonight.

Brave New Foundation, a sister entity of Brave New Films, released a statement tonight defending the video and refusing Americans for Prosperity's demand that they retract the video. The NC chapter of AFP sent out its own statement tonight from Perry Woods, one of the people interviewed in the film, denying that AFP and the Koch brothers were involved in the election.

In Brave New Foundation's statement, the California-based liberal group says the conservative AFP "is trying to back-peddle and disassociate its involvement to re-segregate public schools."

CORRECTED TO REFLECT THAT BRAVE NEW FILMS AND BRAVE NEW FOUNDATION ARE SISTER ENTITIES

A new video from a liberal group is accusing the conservative Koch brothers of having bought the Wake County school board elections in 2009 in an attempt to resegregate the school system.

The 11-minute video, released today by Brave New Films founded by Robert Greenwald, is part of a series of films attacking the Koch brothers. For this film, a variety of local supporters of the old diversity policy go on to blame the Koch brothers for the 2009 election results and ignore the notion that there was any large grassroots support for the changes.

"In 2009, the Koch brothers tried the destroy the Wake County Public School system," says a blurb flashed on the screen.
