John Dickerson: John McCain also served in the Navy, of course, passed away recently. What are your thoughts on his passing?

Jimmy Carter: Well, John McCain's service in the Navy made me proud. His personal heroism has been proven.

So I think that John McCain was admirable as a naval officer, as human being and as a member of the US Senate.
