Sen. Tom Coburn, R-Okla., explained to a town hall of his constituents that he wanted to call a national Constitutional Convention after reading Mark Levin’s new book, The Liberty Amendments.

“I used to have a great fear of constitutional conventions,” Coburn said according to the Tulsa World. “I have a great fear now of not having one.”

As the Tulsa World notes, a national convention is called by two-thirds of the state legislatures and is one of two ways the U.S. Constitution can be amended.

Coburn made his remarks in Muskogee, Okla.
