How does de la Cruz intend to stop arms shipments without any congressional representation to push legislation to do so?
If Congress says money must be spent on sending Israel weapons, then the president has to follow that in some capacity. The president could try to stop shipments, but that would result in a swift court case, and the president would be compelled to continue sending weapons. The executive branch has discretion in how to do so, but it unfortunately does not have the authority to end it.
You need Congress if you’re going to stop all shipments. Alternatively I suppose you could try to have the judiciary in your favor, but that means de la Cruz now needs the Supreme Court on her side.
It’s a complete misconception in American society and politics that the president can do anything. They’re certainly the most powerful single individual, but Congress is still much stronger.
The Party for Socialism and Liberation would be much better served trying to win Congressional races so they can push for bills to end weapon shipments. If they could take a number of strong Republican districts with their message, it would give them a lot more influence.
