The state attorney general filed a complaint earlier this week against a right-leaning think tank, alleging it violated campaign finance laws.

The attorney general’s office announced on Friday that it filed a complaint in Thurston County Superior Court against the Olympia-based Freedom Foundation — a think tank described as “conservative,” “libertarian,” or “free-market,” depending on who you ask.

The attorney general alleges that the foundation failed to properly file independent expenditure reports disclosing money it spent to oppose statewide ballot measures — in particular, the foundation has launched a campaign opposing Initiative 1501, which concerns raising penalties for fraud and identity theft perpetrated against senior citizens.

The initiative was bankrolled by the Service Employees International Union (SEIU), which is embroiled in a long and bitter feud with the Freedom Foundation.
