Oops, republican presidential candidate John McCain did it again. After singing about bombing Iran, now he makes a joke about cigarettes meant to kill Iranians. At least he intended to be a joke.

According to The Associated Press, a reporter from the agency asked John McCain about a report which showed that $158 million in cigarettes have been sent to Iran during George W. Bush's presidency, despite that U.S. had exports restrictions to that country.

The presidential candidate, who was with his wife at the Primanti Brothers restaurant, said that it could have been a “way of killing them,” adding that he intended it to be a joke.

“Maybe that's a way of killing them. I meant that as a joke, as a person who hasn’t had a cigarette in 28 years,” said John McCain, according to The Associated Press. His wife corrected him, saying it had been 29 years.

He also said that it was the first time he heard about the situation and he would have a better answer next time, after he would examine the issue more thoroughly.

Last year, at a campaign meeting in South Carolina, John McCain was asked if there was a plan to attack Iran. He began singing: “Bomb bomb bomb, bomb bomb Iran,” after the song “Barbara Ann.”
