Here's McCain spokesman Brian Rogers statement, via TPM Election Central:
If you didn't think this was a coordinated attack on John McCain's credentials before, it's clear now that it is. Barack Obama's surrogates are telling the McCain campaign to "calm down" about attacks on his military record? Seriously? Now somehow Wes Clark's attacks are John McCain's fault? It's absurd. If Barack Obama can't control his own surrogate operation, how can he be trusted to run the country?

Webb press secretary Kimberly Hunter denied there was any coordination and reiterated that Webb wasn't criticizing McCain's service in the military. Here's her statement, also given to TPM:

I can tell you that Senator Webb has never spoken with Senator Obama about this issue nor has he spoken to Wesley Clark. Senator Webb's comments were not targeted at McCain's military service. He has consistently called for politicians not to insert politics into military service. This is the exact same argument that he used against Lindsay Graham last year in their Meet the Press interview regarding objections to giving troops adequate dwell time at home.Senator Webb has never, and would never, demean the service of anyone who has stepped forward to serve our country. To the contrary, he was calling on those on all sides of the debate to refrain from implying that their political views are representative of the military writ large.
