Donald Trump’s war against Iran is beginning to crack inside the U.S. Senate - and this time the fractures are coming from within the Republican Party itself. Republicans once again blocked a Democratic resolution on Wednesday that sought to end the war, but the narrow result made clear that support for the White House’s military course is beginning to erode.
The measure failed by only a single vote, 49 to 50. Most significant was the reversal by Lisa Murkowski of Alaska. The Republican senator voted against the war for the first time after previously supporting the operations since late February. Susan Collins of Maine and Rand Paul of Kentucky had already voted against the administration’s military line earlier. The number of Republican senators openly expressing doubts is now growing.
The vote became even more unusual because John Fetterman was the only Democrat to vote against the resolution. In doing so, Fetterman delivered the decisive vote for Trump. While parts of the Republican Party are beginning to distance themselves from Trump’s war policy, the senator from Pennsylvania sided with the White House. That position now demonstrates just how unstable the political atmosphere in Washington has become.
John Fetterman, America’s Loneliest Democrat (?)
His vote has triggered reactions within his own party and among the public that no team of political advisers can spin away anymore. It is not his first break from the party line. Again and again, he votes alongside Trump. A senator who spends every other vote mowing the opponent’s lawn is not an independent thinker, but a political defector in slow motion. Someone who votes this way is not building a political profile, but digging a grave. Fetterman is already standing inside it with both feet while waving at the cameras as though this were a campaign appearance. It is not. It is the funeral, and he is the only mourner attending.
What makes the situation especially delicate for the White House is not only the vote itself, but the mood behind it. Several Republicans are now demanding that Congress regain greater authority over the war. The Trump administration still insists that it does not require renewed congressional approval. The White House argues that hostilities with Iran have ended because a ceasefire is now in place.
That exact argument is now causing growing unease inside the Senate. Under the American War Powers Act of 1973, a president must seek congressional authorization after sixty days of military operations. The administration, however, continues attempting to bypass that requirement. Defense Secretary Pete Hegseth even openly stated before Congress that the United States could launch new attacks against Iran at any time without seeking fresh approval from lawmakers. An entirely absurd statement.
Lisa Murkowski directly challenged that argument in unusually blunt terms. During a hearing, she pointed to American troops and warships that remain stationed throughout the region. “It does not look like hostilities have ended,” she said.
Nervousness is also growing within the Republican Party over the economic consequences of the war. Rising gasoline prices, tensions surrounding the Strait of Hormuz, and uncertainty ahead of the midterm elections are creating increasing pressure behind the scenes. Leading Republicans still publicly defend the war aggressively. John Barrasso declared in the Senate that Iran’s economy had effectively collapsed and that the Iranian leadership had been neutralized. At the same time, he accused Democrats of trying to weaken Trump politically ahead of his upcoming trip to China.
But the doubts are no longer disappearing. Mike Rounds of South Dakota stated that Congress and the White House must finally clarify their shared constitutional responsibilities. That sentence increasingly reveals the Republicans’ real problem. The war is steadily evolving into a conflict over who in the United States still has the authority to decide on military operations.
Democrats now intend to increase pressure week after week. Tim Kaine has already announced additional votes and openly stated that the day will come when the Senate tells the president to end this war. Jeff Merkley of Oregon has also begun speaking openly about a visible loss of support and growing skepticism within the Republican Party.
Trump still retains the majority behind him for now. But Wednesday’s vote demonstrated clearly for the first time that resistance to this war is no longer coming only from Democrats, with the exception of Fetterman.
