Washington (CNN) - Arizona, please do not read on.
Republican Sen. John McCain joked that he hopes CBS does not air in the Grand Canyon state so that his constituents don't hear what he has to say next: "I respect Hillary Clinton."
Bob Schieffer told McCain on "Face the Nation" that Clinton has said he is her "favorite Republican." Is the feeling mutual? Schieffer asked.
"I hope this program is blacked out in Arizona. Please cut," he joked Sunday.
Appearing with long-time friend and ally Sen. Lindsey Graham, R-South Carolina, McCain discussed immigration, Iraq and terrorism. But Hillary Clinton was the "one question I can't let you get away without asking," said Schieffer.
McCain had nothing but kind words for Clinton and parlayed his response into a broader push for bipartisanship.
"I respect Secretary, Senator Clinton. I respect her views. We have had disagreements on a number of issues. But I think it's my job to work with every president - if she is, regrettably, if she obtains the presidency," he said, before noting his work with Sen. Bernie Sanders, I-Vermont, on a bill to fix the Department of Veterans Affairs.
"You've got to reach across the aisle and work together on certain issues. And I'm not only not embarrassed about that, I'm proud of it," he said.
During an interview with ABC News, Clinton commended McCain when asked who her favorite Republican in Congress is.
"He and I have traveled a lot, we argue a lot, and he goes off on something that I disagree with, you know I admire him, and I spend a lot of time with him," he said.
The two served together on the Senate Armed Services Committee, which required extensive travel.
In April, McCain hosted the former secretary of State at the Sedona Forum at his McCain Institute for International Leadership. In a news release at the time, he called her "my friend."
