Veteran Fox News anchor Chris Wallace on Wednesday doubted whether President Trump would ever concede the 2020 presidential election to President-elect Joe Biden during remarks he made to accept an award. 

Major news networks called the presidential race for Joe Biden on Saturday, but Trump has refused to accept defeat, alleging without evidence that there was widespread voter fraud amid the expanded use of mail-in ballots. 

The Trump campaign has mounted legal battles in several battleground states to contest the results including Michigan, Pennsylvania and Georgia, where Biden leads the Republican in some cases by tens of thousands of votes. 

“Well, I don’t think we’re going to see a presidential concession,” Wallace said after he was presented with the Poynter Institute’s Lifetime Achievement Award.

“I think he clearly is going to pursue all of his legal cases. And as a reporter and I hope a fair one, we have to be open to the possibility that he will find something, and his team will find something serious.” 

The journalist, who also served as the moderator of the first presidential debate between Biden and Trump earlier this year, said if the Trump campaign does find substantial evidence of fraud, it would have to be enough to influence election results. 

“You’ve got to find serious fraud and you have to find fraud of a dimension that even if it’s true, it would actually flip the election,” he said. 

Critics of Trump have said his refusal to concede the election undermines the electoral process, with some warning that the refusal could threaten national security.

Biden said on Tuesday that Trump’s actions are an “embarrassment” for the country and predicted it will have a negative effect on Trump’s legacy. 

Wallace mentioned the case of a Pennsylvania postal worker who on Tuesday recanted allegations of ballot harvesting while predicting it is unlikely the Trump campaign’s lawsuits go far in court. 

“There was just a case in Pennsylvania this evening, you may not have heard about, where a poll worker had claimed that she had been the witness to all manner of terrible things and she just recanted that testimony or that claim. So we’ll have to wait and see,” Wallace said. 

“I will say, so far, every case of substance has been thrown out,” he continued. “I don’t think you’ll see the president concede in the next two weeks. I’m not sure you’ll ever see him concede. I hope at a certain point, though, that if he doesn’t come up with the goods, that either he or the people around him will move on and we’ll have a more normal transition.”

Trump clashed with Wallace on more than one occasion during the campaign, accusing him of being biased against him and not asking Biden tough enough questions. 

Trump has also been critical of Fox News, specifically the network’s pollsters and decision desk.
