Sen. Tom Coburn, R-Okla., plans to push for a constitutional convention after he retires in the hopes that the drafting process would produce a smaller federal government.

"I'm going to be involved with the Convention of States. I'm going to try to motivate so that that happens. I think that's the only answer," Coburn told the Huffington Post's Jon Ward. "I'm just going to go around and talk about why it's needed, and try to convince state legislatures to do it."

Convention of States wants a constitutional convention "for the purpose of stopping the runaway power of the federal government." The group behind the drive wants to address federal spending and debt, excessive regulations from federal agencies, Congress' method of "using federal grants to keep the states under its control," and "federal takeover of the decision-making process."

"Washington, D.C., will never voluntarily relinquish meaningful power—no matter who is elected," the group says. "The only rational conclusion is this: unless some political force outside of Washington, D.C., intervenes, the federal government will continue to bankrupt this nation, embezzle the legitimate authority of the states, and destroy the liberty of the people. Rather than securing the blessings of liberty for future generations, Washington, D.C., is on a path that will enslave our children and grandchildren to the debts of the past. The problem is big, but we have a solution."

Coburn made a similar statement to Ward. "We need a balanced budget amendment, we need term limits, we need the oversight capability to limit the bureaucracy in terms of its impact on the private sector," he said. "We need to have that discussion. And I want to tell you, the country's tuned for it."
