AP reporter calls BS on Romney

This is an interesting little aberration, and something you rarely see. A reporter simply couldn't sit still while Wink Martindale told a fib (well, it depends on what the meaning of the word "running" is, for all you righties that had a conniption fit about Clinton parsing words.)

Romney keeps his glued on smile throughout, and admirably maintains his composure. (though of course talking heads tried to imply that he went ballistic) The AP reporter simply won't back down. Romney won't either, clinging desperately to a near meaningless semantic distinction, which therefore insures that it won't end well. It's also interesting to get a glimpse of how Romney's press flack then scolds the reporter for being argumentative with the candidate.

So.... what do you you think about this?

Was the reporter doing his job in calling Romney on this apparent attempt to be deceptive? Did the reporter overstep his bounds by essentially getting into an argument with Romney? Was it a little of both? How do you see it?
