LINCOLN, Neb. (AP) — A former Oklahoma senator says Americans should reclaim control from the federal government by invoking a tactic last used in 1787 that lets states craft constitutional amendments.

Tom Coburn, a senior adviser to the Convention of States Project, rallied with supporters at the Nebraska Capitol on Tuesday to support a legislative resolution calling for a convention of the states.

Holding a convention would require 34 state legislatures to approve applications for one. Nebraska’s application, sponsored by Sen. Laura Ebke of Crete, proposes constitutional amendments curbing federal power, imposing federal fiscal restraints and putting term limits on federal officials.

Five states have approved a convention of states so far. Any proposed amendment coming out of a convention would need to be approved by 38 states.
