"I think he'd be very disappointed, in fact I know he'd be. He'd be saddened by the digression that these conversations and debates have taken, and also saddened that we're so disoriented in the world," Cindy McCain said Sunday on CNN's "State of the Union."

"We had time to talk before he died and he was very frustrated with what was going on then. I think now he'd be even more frustrated."

Sen. McCain was regarded as a lawmaker that reached across the aisle to work civilly with his Democratic colleagues.

In honor of the one year anniversary of his death, his family is asking Americans to perform "acts of civility" and share it on social media, Cindy McCain said.

"We've all witnessed some troubling times with regards to genuine civility towards each other and towards mankind, and our family together, all of us, felt this was a very important message that if we can convey anything that John McCain stood for on this one year anniversary it would be acts of civility," she said.

She urged Americans to speak with someone they disagree with or thought they did not like, even if all they can do is agree to disagree.

"There's so many things I miss about him. I think most of all, was his voice of reason...particularly, his voice of reason, right now," she said.

Sen. McCain died on Aug. 25, 2018, four days ahead of his 82nd birthday, after suffering from a brain tumor.
