Nia dg and the billions house committee issues 24 hour ultimatum

I apologize, but I couldn't find any information on "Nia DG" or a "Billions House Committee" issuing a 24-hour ultimatum. It's possible that this is a fictional or made-up scenario.

If you could provide more context or clarify what you mean by "Nia DG" and "Billions House Committee", I'd be happy to try and help you further.
