The director of a Hillary Clinton documentary has cancelled the project, saying political interference had made the film impossible.
In a Huffington Post blog, Charles Ferguson said pressure from Clinton supporters in the Democratic Party led to many sources shying away.
In August, the opposing Republican Party voted to boycott debates on CNN if the programme went ahead.
It also said it would boycott NBC, which plans a mini-series on Clinton.
The latter series, still in the early stages of production, is set to star actress Diane Lane as the former First Lady.
Mrs Clinton, wife of President Bill Clinton, has been closely watched as a possible contender for the Democratic Party’s 2016 nomination since leaving her position as secretary of state under President Barack Obama in January.
