In Kikkert v. Trump, (WD WA, Oct. 1, 2025), plaintiff, an army veteran and federal taxpayer, sued the President and various members of Congress. According to the court:
Plaintiff alleges that by using federal taxes to fund Israel’s recent military operations, Defendants have breached numerous international treaties, federal statutes, and provisions of the U.S. Constitution.... Plaintiff further alleges that he has standing to bring this suit, claiming that his “$72.72 in 2023 excise taxes are part of the $3.8 billion in annual U.S. military aid to Israel” and said aid is “causing Plaintiff irreparable spiritual harm by forcing him to contravene his faith and his veteran’s oath to defend the Constitution, a sacred text in his religion, and desecrating his familial legal of military service spanning give generations.”
The court dismissed the suit for lack of standing, saying in part:
... [T]he mere fact of being a taxpayer is not enough to establish Article III standing. The only exception to this general rule is a narrow exception provided by Flast v. Cohen.... But the Supreme Court has also “repeatedly emphasized that the Flast exception has a narrow application”...
... Flast and its progeny are primarily focused on Establishment Clause challenges.... Here, however, Plaintiff does not bring an Establishment Clause challenge....
As for his Free Exercise argument, Plaintiff fails to allege specific facts to give rise to Article III standing....
Plaintiff’s claim that the government’s funding of Israeli military operations using federal taxes operations has “force[d] him to commit sacrilege” and is causing “irreparable spiritual distress,” ... does not amount to an alleged injury to his ability to exercise his religion. It is thus insufficient to establish Article III injury-in-fact.
