Sen. Ed Markey (D-Mass.) announced Tuesday he voted to block the Trump administration’s record $1.5 trillion defense budget on the Senate floor — the same day he called for slashing Pentagon spending in half through legislation he introduced last month that would cap national defense authorizations at $750 billion for fiscal year 2027.
“I just voted to block Trump’s defense budget on the Senate floor,” Markey wrote on X. “No more funding for endless war. Slash the Pentagon now.”
The vote referred to a failed cloture motion on proceeding to S.4784, an original bill for FY2027 military activities authorization sponsored by Senate Armed Services Committee Chairman Roger Wicker. The motion failed 50-46, according to Senate floor activity records for July 14, 2026.
The Slash the Pentagon Act
Markey introduced the Slash the Pentagon Act on June 16, 2026, calling for a cap of $750 billion on FY2027 national defense authorizations — roughly half of the Trump administration’s $1.5 trillion request. The bill, designated S.4799 in the 119th Congress, was referred to the Senate Armed Services Committee, where it remains pending.
“We are in the midst of a Pentagon spending spree that is lining the pockets of defense contractors while doing nothing to make our communities safer or our families more secure,” Markey said in his official press release introducing the bill. He argued that the funds redirected from the Pentagon could instead be invested in healthcare, education, housing and infrastructure, which he described as the real foundations of national security.
Markey specifically cited the Iran war as a driving motivation. “The Trump administration has launched an illegal war in Iran without authorization from Congress, and now they want to spend $1.5 trillion — a record amount — to fund it,” he said. “We need to cut the Pentagon budget in half and invest in the needs of working families.”
What Trump’s Budget Requests
The Trump administration’s FY2027 budget request totals approximately $1.5 trillion in national defense spending — the largest defense request since World War II, according to the White House’s official rebuilding our military fact sheet. The request includes roughly $1.15 trillion in base discretionary spending through regular appropriations and $350 billion through a third budget reconciliation package the administration has branded “Recon 3.0.”
The $350 billion reconciliation package targets munitions production, shipbuilding, the Golden Dome missile defense system, drone development and artificial intelligence. If passed, the combined request would represent a roughly 44 percent increase over the FY2026 defense budget — the largest single-year percentage jump in modern American history outside of wartime emergency supplementals, per the official FY2027 White House budget document.
The Pentagon has argued the increase is essential to close critical gaps in munitions stockpiles revealed by the Iran war and the war in Ukraine, modernize a fleet of aging weapons systems, rebuild the defense industrial base and fulfill the NATO commitment to spend 5 percent of GDP on defense. The FY2027 National Defense Authorization Act — the underlying legislation Wicker was attempting to advance Tuesday — is the primary vehicle for authorizing those expenditures and setting policy for the armed forces.
The Senate Fight Over the Budget
Tuesday’s failed cloture vote reflects deep Senate divisions over the scale of the defense request. While Republicans broadly support increased defense spending, Senate Appropriations Chairman Susan Collins and Armed Services Chairman Wicker have expressed reservations about the $350 billion reconciliation component, arguing major defense programs deserve the full scrutiny of the regular appropriations process rather than the expedited reconciliation track.
Democrats, led by Markey and others including Sen. Bernie Sanders, have argued the opposite — that the overall request is too large regardless of the mechanism, and that the Iran war has expanded the Pentagon’s budget demands while producing unclear strategic results. Sanders introduced a separate War Powers Resolution to end the Iran conflict, which also failed on a party-line vote, per his official Senate press release.
Markey’s Broader Critique
Markey has been among the Senate’s most consistent voices for cutting defense spending throughout his career. He has been a member of the Senate Foreign Relations Committee and Senate Commerce Committee and co-authored major environmental and foreign policy legislation over four decades in Congress. His Slash the Pentagon Act has no cosponsors listed as of the date of introduction, reflecting the challenge of building a coalition for deep defense cuts even within the Democratic caucus.
The bill nonetheless serves as a marker of the progressive left’s position in the ongoing NDAA debate. While the Slash the Pentagon Act has no prospect of passing the current Senate, its introduction and Markey’s floor vote Tuesday define one pole of the debate — against a backdrop in which the administration is simultaneously conducting active military operations in Iran, maintaining a naval blockade on Iranian ports and asking Congress for another $350 billion in defense funds on top of the largest base defense request in modern history.
Markey’s post on Tuesday came just hours after Treasury Secretary Scott Bessent announced more than 50 new sanctions designations against Iran’s illicit shipping network and CENTCOM confirmed ongoing strikes against Iranian targets in and around the Strait of Hormuz. The juxtaposition — between the administration’s escalating military posture and a Democratic senator calling to cut the Pentagon budget in half — captured the breadth of the political divide over the Iran war heading into the November midterms.
