CNN Films and NBC Entertainment on Monday canceled plans to produce programs about former secretary of state Hillary Clinton, putting and end to projects that had sparked considerable political controversy.

CNN Films had planned to produce a documentary about the former secretary of state, while NBC Entertainment was moving ahead on a miniseries.

CNN decided to shelve its plans after Charles Ferguson, the director it tapped to produce the documentary, decided to abandon the project. In a lengthy piece published on the Huffington Post Web site Monday morning, Ferguson explained that he felt compelled to shelve it over opposition to the idea from both Clinton allies and opponents, which triggered a widespread lack of cooperation among potential interviewees.
