BILLINGS, Mont. (AP) — Republicans in Congress say a 40-year-old law meant to protect animals and plants from extinction has become bogged down by litigation and is in desperate need of an overhaul.

Thirteen GOP lawmakers plan today to release a report detailing their proposed changes to the Endangered Species Act.

Proponents credit the act with staving off extinction for hundreds of species, including the bald eagle, American alligator and the gray whale.
