Trump campaign sent Cease-And-Desist-Letter to CNN, demanding retraction of poll showing Biden leading

CNN reported that CNN President Jeff Zucker had received a cease and desist letter from the Trump campaign, demanding the network to retract a recent poll in which Biden took a 14-point lead over Trump. The poll, conducted by SSRS, was released on Monday and showed a result of 55% to 41% in favour of Biden.
In the letter, the Trump campaign claimed the poll was "designed to mislead American voters through a biased questionnaire and skewed sampling" and that the poll would "cause voter suppression, stifle momentum and enthusiasm for the President, and present a false view generally of the actual support across America for the President."
CNN has rejected the demand and CNN spokesman Matt Dornic said: "We stand by our poll."
