From a Washington Post story by Caroline Anders headlined “Judge throws out Trump ‘big lie’ defamation lawsuit against CNN”:

A federal judge dismissed Donald Trump’s lawsuit against CNN, in which the former president said the network defamed him by associating him with Adolf Hitler.
Trump argued that by using the phrase the “big lie” in reference to his unfounded claim that the 2020 presidential election was stolen, the network created an unfair association between him and the Nazi regime.
