The conservative activist James O’Keefe has posted a new hidden-camera video purportedly showing a staff member at a Los Angeles office of the Acorn community-organizing group assisting a would-be prostitution operation, says the Los Angeles Times.

Similar videos shot by Mr. O’Keefe at Washington and Baltimore Acorn offices, which were released two months ago, fueled Republican ire at the antipoverty and housing-advocacy group, which has lost federal money and started an internal investigation as the result of the controversy.

Acorn officials disputed the validity of the latest tape, calling it “clearly doctored.” They said the L.A. staff member, who left the organization last month for unrelated reasons, offered no help in setting up a brothel and instead attempted to steer Mr. O’Keefe and a female colleague (who was posing as an abused sex worker) to another nonprofit organization that deals with abuse cases.
