Gore's anti-penny activism first came to public attention when he posted a calculation of the cost of the penny to Americans in terms of wasted time ($5 billion) while a graduate student at the University of California, Berkeley. He is the founder of the organization "Citizens to Retire the Penny", through which he advocates for the elimination of the penny. Gore was interviewed on
the Colbert Report in 2008 on the subject of pennies; he also endorsed
Barack Obama's
presidential campaign (this interview took place before the 2008 election). ==References==
