Washington state auditor Troy Kelley says he has fully cooperated with federal officials on questions related to financial activities at a business he previously owned. He said all of his actions over the years have been "lawful and appropriate."

Kelley returned to his Olympia office on Monday following a week where federal agents raided his home and the Justice Department subpoenaed records relating to an employee who was also a former business associate. Kelley issued a written statement through his spokesman, who said the auditor had no plans to appear publicly or answer media questions.

Information continues to come out about the wide net the federal government has cast, ranging from Kelley's expenses from his time as a lawmaker to seeking information from the state Department of Revenue.
