Twitter received nearly $200,000 for campaign ads from 2012 through 2019 but failed to follow Washington state disclosure laws, the attorney-general's office said in a statement.
The company failed to maintain the required records for at least 38 Washington candidates and committees that reported paying $194,550 for political advertising on Twitter's platform since 2012, according to papers filed at the King County Superior Court.
"We ended all political advertising in November 2019 in line with our belief that the reach of political speech should be earned and not bought," a Twitter spokesperson said.
"This resolution is reflective of our commitment to transparency and accountability."
