MONTPELIER, VT. >> The Vermont Senate is set to debate a bill that would ban the sale of ivory and rhinoceros horn in Vermont, with an exception. Advocates want to dampen the international market for those materials, because of the damage they do to populations of both rhinos and African elephants.

There's also concern illicit sales of ivory and rhino horn help fund terrorist groups.

Antiques and dealers of old pianos have complained that the call to ban the sale especially of ivory could severely dampen their business.

The Senate version of the bill contains an exception for products that contain ivory that were sold legally when they were manufactured, providing there's a notarized statement of origin accompanying the item.
