Thanks to Rus Thompson for bringing this story to my attention.
Apparently, Oklahoma has reminded the federal government that the 10th Amendment to the US Constitution says states come first ... and the feds get leftovers if there are any. A Joint Resolution claiming sovereignty under the Tenth Amendment to the Constitution of the United States over certain powers; serving notice to the federal government to cease and desist certain mandates; and directing distribution.
I have been mentioning for years that the 10th Amendment is the forgotten amendment. I also like to remind people that outside of the US, the words "state" and "nation" are synonyms. Essentially, the US is designed as a collection of countries with a common cause of freedom and joined together for commond defense. But laws are allowed - even expected - to be different from state to state. With the feds creating all their own laws, though ... the state is being diluted.
