Jeffrey Thompson steps down from D.C. Chartered Health Plan

WASHINGTON (AP) - The businessman at the center of a federal investigation into campaign finance in the District of Columbia has stepped down from the board of the health-care company he owns.

A spokeswoman for D.C. Chartered Health Plan says Jeffrey Thompson resigned from the board on Friday.

Chartered spokeswoman Karen Dale also says the company's chief executive has notified city regulators that he's seeking to purchase the firm.

David Wolf, a former executive vice president at CareFirst BlueCross BlueShield, is replacing Thompson as board chairman at Chartered.

Thompson's offices and home were searched by federal agents last month, and federal authorities have delivered subpoenas to elected officials in the district seeking information about his campaign contributions.

Chartered holds a contract worth $322 million annually to manage health care for low-income city residents
