The law NEA 1976 also allows the congress to terminate the declaration. The president can veto. The congress can override or not.
That is correct, but that is not what is being said. Power of the Purse and Separation of Powers are the rational being put forward for not voting in support. If the feckless Repubs disagree with the Emergency Declaration because they disagree with the policy, then fine, let the process work as you stated. But these spineless Repubs are trying to have it both ways and trying to wrap themselves in the Constitution to cover up their spinelessness — that’s BS.
