NEW YORK (AP) - An ad by John McCain criticizing Barack Obama first ran Wednesday in Colorado, but there is no data yet on whether the ad also appeared on Thursday, the anniversary of the Sept. 11 terrorist attacks.
Both the Obama and McCain campaigns had agreed to refrain from negative attacks on Thursday to observe the anniversary.
The McCain campaign announced the new ad on Friday, even though it had already run two days before.
Evan Tracey, who tracks political ads as head of TNS Media Intelligence/Campaign Media Analysis Group, said the company's tracking devices show the ad aired on Sept. 10, and that there's no data yet to show that it also ran on Thursday.
McCain campaign spokesman Brian Rogers also said there is no evidence it did.
The 30-second ad criticizes Obama's campaign for what the Republicans call "disrespectful" treatment of McCain's running mate, Alaska Gov. Sarah Palin.
