250 years of America

America is celebrating its semiquincentennial. The Founding Fathers had an idea for a system of government: three separate branches, with checks and balances so each could make sure the others didn’t overreach. As America marks its big birthday, how is that holding up?

John Prideaux, executive editor and host of “Checks and Balance”
Charlotte Howard, U.S. editor
