Rubio in home state vowing to solve national debt crisis

Republican presidential candidate Marco Rubio says he will solve the nation's debt crisis by reforming Medicare and Social Security, forcing Congress to balance the federal budget and promoting economic growth.

He says Democrats and Republicans alike are to blame for a national debt that is expected to hit $20 trillion next year, saying it's the "most predictable crisis in American history."

Rubio pledges he "will stop this irresponsible spending and solve our nation's debt crisis' in prepared remarks before a town hall meeting Monday in Sarasota, Fla.

He also says he opposes a "value-added tax," which is akin to a sales tax and would replace the current payroll and corporate income tax.

Rubio did not mention them by name, but Ted Cruz and Rand Paul have advocated a value-added tax.
