"I think my husband would be very pleased," Cindy McCain, who endorsed Biden and is serving as part of his transition team, told CNN late Monday.

The Associated Press last week called the McCains' home state of Arizona for Biden. The former vice president currently leads Trump, 290 electoral votes to 214 electoral votes, according to the news service. It has not yet called North Carolina, Alaska or Georgia. 

Cindy McCain on Monday also said she believes that Biden can unify the nation and work with lawmakers across the aisle, telling CNN that “I would not have supported Vice President Biden if I had thought ... anything but that." 

"That is the difference in President-elect Biden with regards to this White House," she said. "I believe they can get things done and I also think that they're going to heal the country by working that way — and that's of course what we all want."

Cindy McCain endorsed Biden in September. 

“My husband John lived by a code: country first. We are Republicans, yes, but Americans foremost. There's only one candidate in this race who stands up for our values as a nation, and that is @JoeBiden,” she tweeted at the time.

She also appeared at the Democratic National Convention, where she discussed Biden’s friendship with John McCain. 

The New York Times reported last week that Trump's top campaign aides attempted to stop him from attacking John McCain in hopes of winning Arizona. Trump has long feuded with the McCain family, lashing out at the former lawmaker even after his death.
