CPI:

You probably don’t give much thought to the three-digit code on the back of your credit card. But a small, bipartisan group of lawmakers thinks political campaigns should be paying a lot more attention to them — in order to keep illicit money from coming into U.S. elections.

Those digits are the focus of a new bill called the “Stop Foreign Donations Affecting Our Elections Act.” The legislation’s main sponsor is Republican Rep. Paul Gosar of Arizona, a member of the ultraconservative House Freedom Caucus who gained notoriety forboycotting Pope Francis’s address to Congress in September.

Supporters of the legislation say that without the additional verification, foreigners — or others with designs on using fraudulent credit cards — could hypothetically funnel money to political candidates.
