"Many lessons here-number one, no sense of humor on the campaign trail. I swear off telling any jokes," Holtz-Eakin told CNN's Wolf Blitzer. He went on to add that he wouldn't talk about the history of technology anymore either.
Holtz-Eakin came under fire earlier this week for implying that McCain invented the BlackBerry. When asked during a press briefing on Tuesday what McCain did as chairman of the Senate Commerce Committee, Holtz-Eakin held up his Blackberry and said: "He did this".
"Telecommunications of the United States is a premier innovation in the past 15 years, comes right through the Commerce Committee. So you're looking at the miracle John McCain helped create and that's what he did," he went on to say.
While Holtz-Eakin reiterated his point that McCain was involved with telecommunications advancements, the adviser claimed that his comment was nothing more than a bad joke.
"It was not just badly told, it was ill-timed," he laughed.
"But you know, these things happen."
