Washington state has strict laws regarding political advertising
According to state laws, advertisers are required to collect information on the sources and payments of political advertising. This data must be made available to anyone for public inspection.
AG Ferguson says that Facebook and Google have failed to respond to queries about political ads that ran inside the state. Both Google and Facebook should have collected and later provided details such as:
The name of the candidate or measure supported or opposed;
The dates the advertiser provided the service;
The name and address of the person who sponsored the advertising;
The total cost of the advertising, who paid for it (which may be different than the sponsor) and what method of payment they used.
