The state of Washington is suing Facebook and Google over allegations that the two companies violated campaign finance laws.

Washington attorney general Bob Ferguson announced that his office filed two lawsuits this week against the two tech giants, alleging they failed to maintain records on entities that have purchased political ads on their platforms, violating state campaign finance laws.

Additionally, under the state’s campaign finance laws, advertisers are required to disclose information on who purchased political advertisements to the public.

Some of the information that Washington state campaign finance laws requires advertisers to keep on political advertising include the name and address of the person who sponsored the ad, the total costs of the ad campaigns, and when they were purchased.

The Washington Attorney General’s office said that over the past decade, “Washington candidates and political committees reported about $3.4 million in payments to Facebook and $1.5 million to Google related to advertising.”
