The ads came from 470 Russian-linked accounts and pages, which Facebook said earlier this month, appeared designed to influence public opinion. "When someone buys political ads on TV or other media, they're required by law to disclose who paid for them," Zuckerberg said. This week several Congressional Democrats called for Facebook and other online advertising businesses such as Twitter to meet more disclosure requirements around political ads, which generally face fewer disclosure rules than political ads on radio and television. Correction: A previous version of this story stated that Facebook said 407 fake Facebook accounts and Pages linked to Russia bought political ads on the social network over the past two years. In fact, Facebook said 470 fake Facebook accounts and Pages linked to Russia bought political ads during that time period.
