NEW YORK (AP) — CNN and NBC on Monday backed out of high-profile television projects about Hillary Rodham Clinton they had been working on for months.NBC said it was pulling the plug on a planned four-hour miniseries on the Democratic former first lady and secretary of state. “Hillary,” which was to star Diane Lane in the feature role and appear before the 2016 election, was the target of external protests and internal unhappiness at NBC.Earlier Monday, an Academy Award-winning filmmaker who was making a documentary about Clinton for CNN said that he was backing out because few people would cooperate with him. The network said the film would not be produced.The Republican National Committee had protested both projects, fearing they would lionize Clinton when she might be a candidate for president.
