Republican state Sen. Tom Buford of Kentucky listens to opening remarks at a balanced budget planning convention at the Arizona Capitol in Phoenix on Sept. 12, 2017. Lawmakers from 19 states are trying to develop a plan in Arizona this week for carrying out a growing, but unlikely, national effort to amend the Constitution to require a balanced U.S. budget. The plan is to add an amendment through a convention, a long-shot effort that has never been successfully done. (AP Photo/Bob Christie)
