Obama suggested the idea to McCain Friday afternoon when the Democratic presidential nominee called his Republican counterpart Friday, the day after the GOP convention ended, to congratulate him on his convention speech.
"[Obama] called after the convention speech, and over the course of the
discussion they mutually agreed to meet jointly in New York," said McCain spokesman Tucker Bounds.
The two men went to Ground Zero Thursday, entering the site together. Both candidates exchanged brief remarks and spoke with some of those on hand for the commemoration.
