The lawfare is only delaying the inevitable. There is a 0% chance that the supreme court rules the chief executive/President is barred from having his subordinates perform an audit of executive agencies. And in that regard, Trump is setting up a direct challenge to the Impoundment Control Act. There's a good chance he wins that case as well.
You might want to review the Impoundment Control Act of 1974.
In Trump's telling, presidents were allowed to freely wield impoundment power until 1974. That's when the government, during the Watergate era, enacted the Impoundment Control Act, which restricts presidents from unilaterally impounding funds.
"This disaster of a law is clearly unconstitutional a blatant violation of the separation of powers," Trump said.
However, a long line of legal scholars, officials and judges from both major political parties
including Brett Kavanaugh, who was appointed by Trump to the Supreme Court has rejected the idea that the president has a constitutional power to ignore spending laws. They say that the Constitution clearly gives Congress the power of the purse and that this includes the power to tell the executive branch how much
and how little to spend on things (when those spending directives have passed both houses of Congress and been signed into law by a president, or when, in the face of a presidential veto, Congress passes the spending law with a supermajority in both chambers).
