No Funding for Trump’s Unconstitutional War on Iran
March 12, 2026
Dear U.S. Senators and U.S. Representatives,
We, the undersigned 251 organizations, have a range of institutional missions and mandates, but are united in seeking an end to an unconstitutional, unauthorized U.S. war. We therefore urge you to vote against any additional funding for Trump’s unconstitutional war on Iran, including the reported supplemental appropriations bill that could provide $50 billion or more for this devastating war.
By launching a war against Iran, Trump has violated the Constitution, defied international law, flouted the will of the American people, and has put millions of lives across the region at risk. A vote for President Trump’s Pentagon supplemental funding package would be a vote to commit the U.S. even further to this crisis, which has already killed seven U.S. servicemembers and nearly 2,000 people from across the region, and which endangers the lives of many more.
The Constitution assigns responsibility for authorizing war solely to Congress to ensure that the president does not unilaterally impose the costs and tradeoffs of armed conflict. Congress and the administration have slashed crucial programs as Americans experience soaring economic costs across the board. Waging a war of choice that costs an estimated $1 billion a day not only fails to address the economic squeeze and healthcare crisis facing working Americans, it also diverts federal funding that could otherwise be utilized.
The Pentagon budget already now totals more than $1 trillion, after the extra $150 billion the agency received in the tax and budget reconciliation bill. The $50 billion that the administration reportedly seeks for a new Pentagon supplemental would be enough to restore food assistance for four million Americans that was taken away in the tax and budget reconciliation bill, establish universal pre-K education, and pay for the annual construction of more than 100,000 units of housing, among other possible priorities. Congress must not allow the illegal commencement of hostilities to force a de facto decision to prioritize warmaking over other needs.
The choice before Congress is whether it will choose to prevent this unconstitutional war from dragging out and potentially escalating or enabling dangerous and deadly protracted conflict. We urge you to refuse funding for this illegal war that Congress never authorized and a majority of the American people oppose.
Sincerely,
