The Secretary of the Treasury can/should/will pay the interest on the debt without the Presidents authority. If the interest goes into default impeach the Treasury Secretary first, get his testimony on the Presidents involvement first. Then go after POTUS.
Watching Lew talking about this is what got me thinking along these lines in the first place. Ol’ “loop-de-loop” signature will put that loop-de-loop on anything Obastard and Jarrett tell him to. He’s not very bright.
As I understand, paying the debt interest obligations is first on the pay list. Before anything else.
The monthly income into the government coffers is many times that needed to service the debt.
IOW for the Country to default on loans would require a conscience effort/edict to bring about. And I don't know if that is even possible.
If that is true then a default can be laid squarely at the feet on Zer0.
