ST. PAUL, Minn. (AP) — The founder of a St. Paul charter school that lost $4.3 million in a hedge fund investment is quitting as superintendent and chief financial officer, the Hmong College Prep Academy board said in a posting on its website. The board said it plans to meet Monday to vote on Christianna Hang’s letter of resignation, which was submitted days after the state auditor’s office determined that the school failed to follow state law and its own policies when it invested $5 million in the hedge fund.
