ALL government agencies have accounting issues. The biggest cause being the fact that they aren't actually accountable to anybody.
The national debt is the greatest threat to the Country. Committing fraud on government money should be treated as TREASON and those who commit massive fraud should be executed.
Of course trying to get that passed through Congress and all of the fraudsters that are elected government officials would be impossible. However is some shit disturber congressman like Matt Gaetz or Rand Paul would sponsor such a bill, it would be interested in seeing who would vote against it. Perhaps they should go to the top of the list of those who should be investigated.
