All McCain has to do is say he doesn't know anything about it other than what he reads in the paper. The investigators and snoopers will do the rest.
Based on what Brit Hume had on Foxnews Special Report,...McCain did not hear what was said....and only knows what his advisers told him....so he may have overdone his apology....LA Times would prefer to leave out some details....but they did mention he didn’t hear the actual comments....
