SEATTLE (AP) — Washington Attorney General Bob Ferguson says he wants two state courts to force initiative sponsor Tim Eyman to turn over business, banking and tax records as part of an investigation of campaign-finance practices.

Ferguson said Thursday he filed petitions in Snohomish and Thurston County Superior Courts asking them to enforce subpoenas issued in the case, seeking documents pertaining to Eyman, his political committees, his for-profit company and a for-profit signature gathering company.

The attorney general says Eyman simply refuses to cooperate. He's turned over what Ferguson described as a "smattering" of records, heavily redacted, but his attorneys never sought a protective order for sensitive records.

Eyman attorney Mark Lamb says he invited Ferguson to examine Eyman's personal tax returns at his office, but he doesn't want to turn them over for fear they might become public.
