Outside of Fox News, anchors were blunt in their dismissals of the president’s claims. On Thursday morning, CNN’s Alisyn Camerota read a thread of Twitter posts in which Mr. Trump said that “we hereby claim the State of Michigan if, in fact, there was a large number of secretly dumped ballots as has been widely reported!”
“Fact-check,” Ms. Camerota said. “There is no evidence of any secretly dumped ballots there or elsewhere.”
On Wednesday night on CNN, the White House correspondent Jim Acosta said some Republicans were criticizing Mr. Trump’s legal attacks “as an ambulance-chasing routine.” Earlier, Michael Smerconish, a radio host and CNN contributor, said, “You can’t just make baseless allegations, and you also can’t talk about ballots that really haven’t even been counted yet as being fundamentally unfair.”
On MSNBC, a network popular with liberal viewers, the host Nicolle Wallace said on Wednesday that the channel was not “going to amplify” the president’s tweets claiming fraud by showing them on television.
“Donald Trump is also tweeting misinformation about alleged fraud — lies so flagrant that they’re almost difficult to find amid the warnings and flags the social media companies have placed on and around them,” Ms. Wallace said.
The MSNBC anchor Brian Williams said, “There is no evidence that these are anything but legally cast votes in states that allow them to be legally cast.”
Not all news coverage sought to debunk the false claims of voter fraud. After Election Day, the conservative cable network One America News posted two videos, together viewed more than 500,000 times, that pre-emptively declared victory for Mr. Trump and made unsubstantiated accusations that Democrats were throwing out Republican ballots.
YouTube removed ads from both videos and tagged them with a warning note. The videos were left up, said Ivy Choi, a YouTube spokeswoman, because although they contain “demonstrably false” information, they do not violate the platform’s guidelines, which prohibit content that misleads or discourages viewers about voting.
