(CNN) - He made headlines for smoking in a web video last week, but Herman Cain's chief-of-staff Mark Block said he'll kick his cigarette habit if his boss gets elected president.
"When he puts his hand on the Bible, sworn in as the 45th president, it's the last day that I have a smoke," said Block in an interview with The Daily Caller on Tuesday.
Block said his pledge to quit smoking was part of a bet he made with Cain.
The unusual web video last week featured the chief-of-staff lighting up after talking about Cain's unconventional campaign.
The ad prompted a wave of speculation over the purpose of the ad, while Block and Cain hit back, saying "America needs to get a sense of humor."
