Some GOP lawmakers were more accepting on Sunday of Biden's lead the day after the former vice president was projected the winner. Others leaned more into Trump’s narrative of voter fraud, championing legal challenges by the Trump campaign.

But Romney told CNN’s “State of the Union” that Trump will “keep on fighting until the very end” over the results. 

“You’re not gonna change the nature of President Trump in these last days, apparently, of his presidency,” Romney said. “He is who he is. And he has a relatively relaxed relationship with the truth.”

The 2012 Republican presidential nominee said the U.S. shouldn’t expect Trump to “respond in the same way” as previous losing presidential candidates, adding that the current president “doesn’t have a choice” on whether to leave the White House. 

The president, in the days following Election Day, has promoted unfounded accusations that voter fraud contributed to Biden’s lead and eventual projected win on Saturday. 

Trump’s campaign has filed several lawsuits to challenge the results in a few battleground states after the president spent months spreading false claims that mail-in ballots could open the election up to fraud. 

Maryland Republican Gov. Larry Hogan said on Sunday that any potential evidence of widespread voter fraud should be released, but he doesn’t believe “anything” will “overturn” the projected election results.

“There are legal processes if you think there are mistakes, but I don’t think we’re gonna see anything that’s gonna overturn this election,” he told CNN’s “State of the Union.” 

“This is the way our system works,” he added. “Whether you like it or not, it's time to get behind the winner of the race.”

“So let’s let this come to its proper conclusion and in the process maximize the number of people who have confidence it was done properly,” Toomey said. 

Biden's projected overall win was called on Saturday seconds after he earned battleground Pennsylvania's 20 electoral votes.

Noem told ABC that “people have signed legal documents ... stating that they saw illegal activities” and noted that The New York Times had reported “clerical errors.”

“No widespread fraud, governor. That's very different,” Stephanopoulos responded.

Later in the interview, Noem said Americans “need to know at least America still functions and we are about doing things right.”

Stephanopoulos quipped back, “It starts with providing evidence. You still have not provided it.”
