During a 2005 radio interview on Orlando talk-radio station WFLA AM 540, Tancredo responded to a questioner asking about the hypothetical U.S. response to a nuclear attack on U.S. cities by al-Qaeda, by saying that one possible response would be to retaliate by "taking out" Muslim holy sites (specifically, Mecca) if it were clearly proven that Islamic terrorists were behind such an attack. Several days later, in an interview on CNN together with James Zogby, Tancredo said that the attack was mentioned merely as a hypothetical response and insisted that there was nothing for which he should apologize.
