Hall of Fame quarterback Brett Favre repaid $600,000 in welfare money to the state of Mississippi this week.
According to ESPN.com, auditor Shad White confirmed the payment but noted that he sent Favre a letter on Oct. 12, informing him he owed $828,000 because of $228,000 in accrued interest.
Favre was initially paid $1.1 million by the Mississippi Community Education Center for multiple speaking engagements but was asked to pay the money back since he didn't appear for them.
Regarding the outstanding $228,000 in interest, White said: "If he does not pay that within 30 days of our demand, the AG will be responsible for enforcing the payment of the interest in court.
