The tug of war between states and the federal government has gotten an additional set of tugs from Sen. John Barrasso (R-Wyo.), drawing on ideas from the Western Governors’ Association on how to revamp the Endangered Species Act.

Barrasso has released a discussion draft bill that envisions a much stronger role for states in shaping recovery plans for endangered species, stirring the fears of environmental activists that states will gain a veto power over efforts to protect species.
