All bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills.
This is the power to authorize spending. Congress must pass legislation to authorize the raising of revenue to be spent on something.

This is the power to appropriate the money from the Treasury. Congress makes the funds available to be spent.

This is the power to spend. The President has the power to execute the laws that appropriated the money from Congress to enable the laws passed by Congress.
Article I Section 9 Clause 7
and a regular Statement and Account of the Receipts and Expenditures of all public Money shall be published from time to time.
This is the power to audit and reconcile that the money spent was used for the purposes that they were authorized and appropriated.
This is what President Trump is trying to do, and this is what Democrats in Congress are trying to get the Courts to block.
President Trump must cite Article I Section 9 and tell the courts that he is taking care that the laws are being faithfully executed, and doesn't recognize their power to interfere with his Executive authority to do so.
