McCain wasn't on stage or, he says, in the building when Cunningham made the comments, but he quickly distanced himself from the radio talk show host after finishing his speech. McCain spoke to a couple hundred people at Memorial Hall in downtown Cincinnati.

"I apologize for it," McCain told reporters, addressing the issue before they had a chance to ask the Arizona senator about Cunningham's comments.

"I did not know about these remarks, but I take responsibility for them. I repudiate them," he said. "My entire campaign I have treated Senator Obama and Senator (Hillary Rodham) Clinton with respect. I will continue to do that throughout this campaign."

McCain called both Democrats "honorable Americans" and said, "I want to dissociate myself with any disparaging remarks that may have been said about them."

Asked whether the use of Obama's middle name — the same as former Iraqi leader Saddam Hussein — is proper, McCain said: "No, it is not. Any comment that is disparaging of either Senator Clinton or Senator Obama is totally inappropriate."

McCain said he didn't know who decided to allow Cunningham to speak but said he was sure it was in coordination with his campaign. He said he didn't hear the comments and has never met Cunningham, but "I will certainly make sure that nothing like that happens again."

Responding to McCain's apology, Obama spokesman Bill Burton said, "It is a sign that if there is a McCain-Obama general election, it can be intensely competitive but the candidates will attempt to keep it respectful and focused on issues."
