McCain's response here via ABC
UPDATE: Sen. John McCain presidential campaign spokesman Tucker Bounds just pounced on this, saying “It’s preposterous for Senator Obama to claim that the leader of his VP selection committee isn’t working for him. Barack Obama has castigated Countrywide Financial, but now that Jim Johnson has been exposed for taking sweetheart deals from Countrywide’s CEO - Obama is in a state of denial. It’s that brand of weak leadership and hypocrisy that shows why Barack Obama has no record of taking courageous stands or making change in Washington.”
