Washington state's attorney general is suing Google and Facebook for allegedly failing to provide adequate public information about who buys election ads on their platforms.

The complaints, filed by the office of Attorney General Bob Ferguson, claim the tech giants haven't properly maintained and publicized information about who's buying election ads. The incomplete data pertains to the names and addresses of buyers, as well as the total cost of those ads and payment methods used.
