A complaint about an anonymous $750,000 donation to the unsuccessful campaign to ban most abortions in South Dakota is being reviewed by Attorney General Larry Long.

Long is also reviewing a complaint about anonymous donations of $471,000 to the unsuccessful campaign to outlaw video lottery. Long says complaints were filed with his office and with Secretary of State Chris Nelson.

The $750,000 donation in the abortion campaign was made to a private corporation set up by state Representative Roger Hunt of Brandon. Hunt says the donor doesn't want to be identified because of fear about possible violence.

Nelson insists that state law is clear and the donor must be revealed.
