Controversy over Variety article on Jeff Zucker's post-CNN plans

Former CNN president Jeff Zucker called for Variety to retract an article claiming he is trying to buy CNN and undermine his successor.
Variety revised the article after criticism but stood by the reporting, while Zucker's camp continues to deny the claims.
The article alleges Zucker badmouthed his successor and fired Chris Cuomo to curry favor with new CNN leadership.
Concerns have been raised about the use of anonymous sources and credibility of some claims in the Variety story.
Variety's editors defend the reporting but added specific denials from Zucker and journalists criticized in the article.
