Defense Secretary Pete Hegseth walked into a packed hearing room in late May 2026 and straight into a wall of bipartisan fury. Lawmakers from both parties wanted to know the same thing: why the administration launched military strikes against Iran on February 28 without asking Congress first, and why, months later, it still had not sought formal authorization to continue.
The hearings, held in both the House and Senate over the course of several days, produced some of the sharpest exchanges between a sitting defense secretary and members of Congress in recent memory. Republicans who typically defer to the Pentagon on military matters joined Democrats in pressing Hegseth on munitions usage, cost estimates, the campaign’s endgame, and the legal basis for bypassing the legislature entirely.
The strikes and the silence that followed
The February 28 strikes against Iranian targets marked the start of a military campaign that the administration has characterized as defensive and limited. But Congress received no advance consultation and no formal request for authorization. Under the War Powers Resolution, the president must notify Congress within 48 hours of committing U.S. forces to hostilities and must withdraw those forces within 60 days unless Congress votes to approve the mission.
A nonpartisan Congressional Research Service analysis specific to the Iran conflict lays out these requirements in detail, including the consultation obligation and the mechanics of the 60-day clock. As of early June 2026, no formal War Powers notification from the White House has appeared in public government records, leaving the legal timeline in dispute.
That gap between the strikes and any formal legal accounting is what drove the hearings. Hegseth’s appearance before the House Armed Services Committee was described as his first congressional testimony since the campaign began, and members made clear they viewed the delay itself as an affront to their constitutional authority.
Hegseth’s ceasefire theory
In the Senate hearing, Hegseth advanced a legal argument that drew immediate pushback. According to reporting from journalists present at the session, he contended that a ceasefire reached with Iran effectively “pauses” the 60-day clock under the War Powers Resolution. If hostilities are suspended, his reasoning went, the countdown stops, and the administration is not required to seek congressional approval until fighting resumes. No direct transcript of his remarks has been published in official congressional archives, so the precise language he used is drawn from journalistic accounts rather than a verbatim record.
Legal scholars and the CRS analysis itself offer no support for this theory. The CRS report addresses the longstanding disagreement between the executive and legislative branches over when “hostilities” begin and end, but it does not endorse the idea that a temporary ceasefire can freeze the statutory deadline. No federal court has ruled on the question, and no previous administration has publicly advanced the argument in this form.
If the theory holds, it would give any president a mechanism to wage an indefinite military campaign by alternating between strikes and pauses, never triggering the withdrawal requirement. Several senators said as much during the hearing, warning that accepting the argument would hollow out the War Powers Resolution entirely.
Congress pushes back with a resolution
The legislative response came in the form of Senate Joint Resolution 163, a measure directing the removal of U.S. forces from hostilities with Iran that have not been authorized by Congress. The resolution’s language was deliberate: by labeling the campaign “hostilities,” sponsors placed it squarely within the War Powers Resolution’s framework and rejected the administration’s framing of the strikes as something short of war.
The resolution’s full text and legislative history are preserved in the official congressional record. A motion to discharge the measure from committee and bring it to the Senate floor reached a vote but failed 49 to 50, with one senator not voting. A single vote kept the resolution bottled up, but the near-miss revealed that almost half the Senate was prepared to force a direct confrontation over the president’s authority to continue the campaign.
The roll call record shows every senator’s position. What it does not fully explain is why individual members voted the way they did. Some opponents of the discharge motion have said publicly that they objected to the procedural tactic rather than the resolution’s substance. Others have stayed quiet. Whether a revised resolution or a second discharge attempt could flip one vote remains an open question, particularly if the ceasefire collapses or public opinion shifts.
What the hearings revealed about costs and strategy
Lawmakers used Pentagon-provided figures to challenge the administration’s strategy on practical grounds. Members asked how long current funding could sustain operations, what trade-offs were being made with other defense priorities, and whether allied nations were contributing meaningfully to the campaign. Hegseth offered broad assurances but, according to reporting from journalists present at the hearings, struggled to provide specifics on an endgame or a timeline for winding down operations.
Official Pentagon documents verifying the cost estimates and munitions data cited during the hearings have not yet appeared in publicly accessible budget justifications or after-action reports. Until they do, outside analysts cannot independently confirm how much the campaign has cost or how heavily U.S. forces have been committed.
Full verbatim transcripts of the hearings have also not been published in primary congressional archives as of early June 2026. The available record consists of reporting from journalists who attended the sessions, which provides a detailed but incomplete picture of the exchanges. Readers should treat those accounts as credible summaries rather than word-for-word records.
Three developments that will shape the war-powers standoff
The confrontation between Congress and the White House over the Iran campaign is far from settled. Three developments will determine where it goes.
First, whether the administration files a formal War Powers notification. Doing so would start or restart the 60-day clock and force the White House to put its legal position on the record. Continued silence on this point will only deepen the standoff.
Second, whether the Senate takes another run at S.J. Res. 163 or a similar measure. The 49-to-50 margin means a single changed vote, or the return of the absent senator, could alter the outcome and compel a floor debate on whether to authorize or end the campaign.
Third, whether any legal challenge to the ceasefire-pause theory reaches federal court. A ruling on whether a temporary halt in fighting can freeze the War Powers clock would set a precedent that extends well beyond Iran, shaping how future presidents interpret their authority to use military force without congressional approval.
At its core, this dispute is about whether the 60-day limit written into the War Powers Resolution still means what it says. If the executive branch can launch strikes against a sovereign nation and then argue that a ceasefire suspends the congressional authorization deadline, the constraint becomes optional. That is not an abstract constitutional question. It determines whether elected representatives retain a binding role in deciding when and how long the country fights, or whether that power belongs to the president alone. The hearings made clear that a significant number of lawmakers, across party lines, are not willing to let that question go unanswered.
