THE U.S. government has nearly $36 trillion of debt on issue and its bonds are the bedrock of the global financial system.

President Donald Trump said Sunday his administration was examining Treasury debt payments for possible fraud and suggested that the country's debt might not be that high - remarks that may unsettle investors who regard the U.S. as creditworthy and its debt as a safe asset.
