"I ask my colleagues to help me support and pass this legislation honoring the bison and designating it as our national mammal," Enzi said. "The bison has and will continue to be a symbol of America, its people and a way of life."
"The bison has been integrally linked to the economic and spiritual lives of many Native American tribes over the centuries," Enzi said. "Since our frontier days, the bison has become a symbol of American strength and determination."
The bipartisan bill is co-sponsored by Sens. Michael Bennet (D-Colo.), Kent Conrad (D-N.D.), John Hoeven (R-N.D.), Mike Johanns (R-Neb.), Jerry Moran (R-Kan.), John Thune (R-S.D.), Mark Udall (D-Colo.), Tom Udall (D-N.M.), and Sheldon Whitehouse (D-R.I.). The National Bison Association, Intertribal Bison Council and Wildlife Conservation Society also support the measure.
