SEATTLE (AP) — Anti-tax activist Tim Eyman has been hit with further sanctions after spending months in contempt of court for refusing to disclose information about his finances in a campaign finance lawsuit against him.

A Thurston County judge ruled Friday Eyman must disclose the source of nearly $800,000 in contributions he’s collected since 2012.

It’s the latest in a series of setbacks for Eyman in an investigation in which Attorney General Bob Ferguson claims that Eyman violated state campaign-finance laws and covertly used his initiative drives to enrich himself.

Eyman has twice been held in contempt of court for refusing to cooperate with court rules. He faces a potential lifetime ban on directing the finances of political committees.
