Arkansas Treasurer Martha Shoffner is to go before a federal judge Monday, after being arrested over the weekend on charges of extortion.
FBI spokeswoman Kimberly Brunell says agents arrested Shoffner Saturday at her home in Newport.
The Democrat serving her second term has been under scrutiny because of how her office has handled state investments.
Legislative auditors say that in 2011, 11 bonds were sold from the state’s investment portfolio before they had matured, resulting in a net loss of more than $434,000 worth of earnings.
