The House has the power of the purse, if they wish they can defund the entire thing and there is not a single thing that can be done about it.
This language is funny as it attempts to use the Senate as a arbiter of the Constitution, and it was never meant to be so, because one legislative body passes a law, a future one may then repeal it no matter the language in the original law.
Agree with most of what you said.
However, we ALL have the power to interpret the Constitution/
The Congress and the President and the SCOTUS have EQUAL powers to interpret and ENFORCE the Constitution.
I think that the legislative and executive branches have been far too docile.
I think BOTH should tell SCOTUS when and where the Supreme Court has been wrong.
