The Republican Party has threatened to boycott whichever television channel in the United States broadcasts a proposed mini-series on the life of possible Democratic candidate Hillary Clinton.
The next presidential election is three years away, but the ABC reports Republicans fear that the proposed series could unfairly influence voters come election time.
A four-part NBC series starring Diane Lane and a feature-length documentary on CNN are set to air in 2014.
Republican National Committee chairman Reince Priebus is threatening to keep presidential debates involving Republican candidates off the channels if they go ahead with what he says amount to political ads for Ms Clinton.
Mr Priebus has written to NBC and CNN executives, objecting to what their "putting a thumb on the scales of the 2016 presidential election".
"Listen, I'm not going to boycott Diane Lane. It's not her fault that she's decided to take a script," he said.
"The fact is, what channel am I going to tune in to see the documentary and the miniseries that is all about promoting Hillary Clinton?
"And at this point, it sounds like it's going to be CNN and NBC, and if that's the case, they're not going to be involved in our debates. Period."
The ABC reports two NBC correspondents - White House chief correspondent Chuck Todd and veteran broadcaster Andrea Mitchell - have also spoken out, suggesting broadcasting the miniseries could damage the reputation of NBC News.
NBC says the miniseries will air before the heat of the campaign and that the NBC News unit is completely independent of NBC Entertainment and had no involvement in the miniseries.
The ABC reports Ms Clinton still has not said she is running, but many political analysts expect she will and her every move is already making news.
