Washington: The Republican Party on Monday threatened to block presidential primary debate partnerships with two US networks if they don`t pull their planned documentaries on Hillary Clinton.
NBC Entertainment is planning a miniseries and CNN is working on a documentary about the Democratic former secretary of state as she mulls a potential run for the White House in 2016.
"As an American company, you have every right to air programming of your choice," Republican National Committee (RNC) chairman Reince Priebus wrote in letters to CNN president Jeff Zucker and NBC Entertainment chairman Robert Greenblatt.
"But as American citizens, certainly you recognize why many are astounded at your actions, which appear to be a major network`s thinly veiled attempt at putting a thumb on the scales of the 2016 presidential election."
Clinton, a former first lady and US senator whose turn as America`s top diplomat earned her widespread praise, is seen as the clear Democratic frontrunner for president.
She has made no announcement of her political plans. But the RNC letters -- more than three years ahead of the 2016 election -- shine a light on the party`s nervousness about a run by Clinton, who narrowly lost the Democratic nomination to Barack Obama in 2008.
"Your credibility as a supposedly unbiased news network will most certainly be jeopardized by the decision to show political favoritism and produce an extended commercial for secretary Clinton`s nascent campaign," Priebus told Zucker.
In a separate statement, Priebus blasted the networks, saying "their actions to promote Secretary Clinton are disturbing and disappointing.
"I hope Americans will question the credibility of these networks and that NBC and CNN will reconsider their partisan actions and cancel these political ads masked as unbiased entertainment.
Should CNN and NBC not agree to pull the productions before the RNC holds its summer meeting beginning August 14, Priebus told the networks he will seek a binding RNC vote "stating that the committee will neither partner with you in 2016 primary debates nor sanction primary debates which you sponsor."
