The state of Washington said it had sued Facebook Inc and Alphabet Inc’s Google for allegedly violating state campaign finance law by failing to maintain information about who buys election ads.
The state’s attorney general, Bob Ferguson, who posted copies of the lawsuits his website, said he was seeking penalties against the companies and an injunction for failing to disclose ad spending in state elections since 2013.
Facebook said it looked forward to resolving the lawsuit quickly after it recently introduced tools for people to see who is buying political ads on its social network.
A representative for Google could not immediately be reached for comment. Like Facebook, Google has pledged to create an online archive of ads that run on its service.
