Additionally, there hasn’t been any public announcement or report on Muir and Davis’s firing on any reliable news source. Therefore, it is reasonable to conclude that ABC did not fire debate moderators David Muir and Linsey Davis.
Nevertheless, the entire rumor reportedly started from the fact that, as per The Daily Beast’s September 12 article, Trump had claimed that the debate moderators had brought “disgrace onto the company”. He also urged the network to fire its entire staff after the debate on September 10.
