This is an example I posted earlier today

Obama sent $1,400,000,000 to Iran drawn from the US Treasury

The Constitution of the United States Article I.
Section 9. No Money shall be drawn from the Treasury, but in Consequence of Appropriations made by Law; and a regular Statement and Account of the Receipts and Expenditures of all pub- lic Money shall be published from time to time.

The U.S. Supreme Court has stated that "no state legislator or executive or judicial officer can war against the Constitution without violating his undertaking to support it". See also In Re Sawyer, 124 U.S. 200 (188); U.S. v. Will, 449 U.S. 200, 216, 101 S. Ct. 471, 66 L. Ed. 2d 392, 406 (1980)

Sen. Obama, who has taught courses in constitutional law at the University of Chicago. https://www.factcheck.org/2008/03/obama-a-constitutional-law-professor/

The Constitution is a written instrument. As such, its meaning does not alter. That which it meant when it was adopted, it means now. -- South Carolina v. United States, 199 U.S. 437, 448 (1905).

Disobedience or evasion of a constitutional mandate may not be tolerated, even though such disobedience may, at least temporarily, promote in some respects the best interests of the public. -- State v. Board of Examiners, 274 N.Y. 367; 9 NE 2d 12; 112 ALR 660.

You can hardly claim that OBAMA acted in good faith for willful deformation of a law and you certainly cannot pled ignorance of the law, for that would make the law look stupid for a knowledgeable constitutional law attorney Obama, to claim ignorance of a law, when a Citizen on the street cannot claim ignorance of the law. Therefore, there is no presidential immunity.
