"The thing about Joy and I is if you extract politics, we are very similar women," McCain explained. "We leave it all out on the table, we fight like boxers, and then we leave and I'm like, 'Do you wanna get a drink? Are we cool?' Neither of us like talking about our personal life on air."
McCain said she and Behar got into "one big [fight] on air" right before the show went on hiatus for the holidays, and that Behar reached out to her around Christmastime to let bygones be bygones.
"She was like, 'I'm over it. Are you over it?' I was like, 'I'm over it,'" McCain said. "She's really funny. At the end of the day, I try and hate her, and I can't! I adore her. She's really fun."
"It's like an older sister I never had, but I'm telling you, I've never had more fun fighting with anyone on TV than I do with Joy Behar," she continued. "I go into battle every day knowing that she is smart, she knows her talking points, she watches as much cable news as I do. We both also enjoy the fights, which is also good. It's liberating to be a woman that can do this on TV, but don't ever worry! People get very anxious, but we always make up."
The daughter of John McCain also explained why she's disappointed in the various Republicans who are trying to step up to the plate and "epically failing."
"No one comes close to my father right now, which is part of why everything's been particularly hard," she said. "Some people that are coming out and trying to be -- you're all epically failing, and it's not good enough. Seriously, like, it's not good enough."
"When this ends -- which, one way or another, Trump will not be president at some point -- we're going to have to come up from the ashes of this and figure out what this party is," she added. "Somebody's gotta lead it, and I don't know who the hell that is right now."
