New York Gov. Andrew Cuomo unintentionally confessed that he has an illegal animal keepsake at an event.

According to ABC News, Cuomo was discussing a trip with his youngest daughter while at an event in Saranac last week. While talking about the trip, he brought up how an eagle feather is now on his mantle in his home. This is against a federal wildlife law.

Cuomo could face a fine of $100,000. A representative from his staff told ABC News that Cuomo will either have to put it back or donate it to a US Fish and Wildlife repository.

The story he told was about a canoe trip in the Adirondacks with his daughter. Cuomo said a bald eagle swooped down near them and a feather fell onto their boat. He said they grabbed the feather and it has been on his fireplace mantle since.

The law that Cuomo unintentionally admitted to breaking was the Bald and Golden Eagle Protection Act. This law prohibits non-Native Americans from disturbing, taking or possessing eagle parts, which includes feathers. The law also makes it illegal to take, possess, sell, purchase, barter, offer to sell, purchase or barter, transport, export or import, at any time or any manner, any bald eagle ... [or any golden eagle], alive or dead, or any part, nest, or egg thereof.
