the argument here is very weak
the idea that one congress can bind future congresses from ever revoking an action of theirs is nonsense.
If a democrat congress passed a law saying “annual contributions from the US government to planned parenthood shall be ‘permanent’ “
would you say, “well we have no choice but to submit to that law”
Of course not
Laws passed by Congress are not at the same level as the US Constitution.
Even the Supreme Court can overrule a Congressional law if they deem it unconstitutional.
