(CNN) - Joe Wurzelbacher, aka Joe the Plumber, has become an integral part of John McCain's presidential bid, but it appears the Arizona senator's campaign and the now-famous Toledo plumber need to work on their communication skills.
McCain aides told CNN's Dana Bash Wurzelbacher would appear with the Republican presidential candidate at his first campaign event in Defiance, Ohio. But in what was a slightly awkward moment for McCain, Wurzelbacher was nowhere to be seen when the Arizona senator called out for him.

A campaign aide later said Wurzelbacher had "decided not to come" and may join McCain later in the day.
But reached at his home by CNN's Mary Snow, Wurzelbacher said it was "news to him" that he was supposed to be at the McCain rally. Wurzelbacher said nobody from the McCain campaign confirmed he was attending the event and called the incident a "miscommunication."
Wurzelbacher also said he is headed to Philadelphia for a charity event unrelated to the campaign and has no plans to meet up with McCain today.
UPDATE: Contacted by CNN a second time, Wurzelbacher said the campaign only called him to confirm after the event in question already took place. He will now try to meet up with McCain later in the day.
Wurzelbacher also said he had gotten an initial call about coming to the morning rally, "but no one called back to confirm," and was "not happy" that McCain had called out his name and he wasn't there.
