The Vice President says the president will decide what’s legal and what isn’t. This isn’t the first time he’s said this:
Trump is so addled he doesn’t have a clue what any of this means. But Vance knows that they are challenging the entire system by saying they have the authority to ignore orders. It’s happened a time or two in the past but even in the most contentious of times the executive has always deferred to the courts and used the normal process to adjudicate the dispute.
They seem to still believe they must adhere to the Supreme Court so perhaps this has to make it all the way up to the top in order to be resolved. And so far they haven’t had much of a problem with them issuing emergency stays so they really don’t need to do this. Simply ignoring the lower courts is an escalation.
