U.S. Senator John Hickenlooper, D-Colo., issued a sharp public rebuke of President Donald Trump’s handling of the war with Iran on Tuesday, declaring “enough is enough” as the American military death toll climbed to 17 and the conflict entered its fifth month with no negotiated resolution in sight.
In a post on X published at 8:34 a.m. on July 21, Hickenlooper wrote that “this weekend was a painful reminder that President Trump’s war isn’t some distant conflict. It’s costing lives and hurting Colorado families.” He continued: “Seventeen heroic U.S. service members have now been tragically killed, with many more injured. More than a hundred billion in taxpayer dollars have been spent for no discernible benefit, while working families struggle to afford gas, groceries, and health care.” Hickenlooper added that “with no deal in sight, President Trump is now escalating this illegal war even further, with no clear justification and no endgame,” and closed with a direct demand: “Enough is enough. The American people overwhelmingly don’t want this war of choice. President Trump needs to end it before more lives are lost and more damage is done.”
The senator’s statement came days after the Pentagon confirmed a third U.S. service member killed within a single weekend, part of what officials described as an intensifying exchange of strikes between American and Iranian forces. U.S. Central Command said the ninth consecutive night of strikes concluded on July 19 at 10 p.m. ET, carried out “to further diminish Iran’s ability to attack commercial vessels and civilian mariners transiting the Strait of Hormuz.” The command added in its statement that “the US military is holding Iran accountable at the Commander in Chief’s direction,” and that “CENTCOM forces remain highly vigilant, focused, lethal, and ready.”
The casualties Hickenlooper referenced stemmed from a violent stretch of fighting beginning July 17, when an Iranian attack on Muwaffaq Salti Air Base in Jordan killed two U.S. service members and left a third missing. CENTCOM reported that Iranian strikes in Jordan injured several additional U.S. service members, and that American personnel had recovered unidentified remains believed to belong to the missing service member. A separate incident in northern Iraq killed another U.S. soldier during the disposal of a downed Iranian attack drone, bringing the total confirmed American military deaths in the conflict to 17 — the exact figure cited in Hickenlooper’s post.
CENTCOM’s retaliatory operations have continued nightly since the Jordan attack. The command said its Saturday-night mission, lasting roughly five and a half hours, was intended to “swiftly punish Islamic Revolutionary Guard Corps forces who launched attacks against American service members in Jordan.” The following night’s operation, CENTCOM said, targeted “Iranian military command centers, air defense and coastal surveillance sites, maritime capabilities, missile and drone launch sites, and communications networks.” Secretary of State Marco Rubio said Sunday that the U.S. “always remains open to a diplomatic solution,” even as the strikes continued.
Hickenlooper’s Tuesday statement is consistent with a position he has held publicly since the war’s earliest weeks. On March 3, ahead of the Senate’s first Iran War Powers Resolution vote, Hickenlooper wrote in an official statement that he was “a YES on the bipartisan Iran War Powers Resolution,” arguing that “the Constitution is clear: Congress decides if we go to war — not the President.” He added at the time that “there has been no articulated goal, strategy, or endgame from the Trump administration for this war that has already resulted in the loss of service members and innocent lives. They very clearly don’t have one.”
He renewed that argument in April after voting again in favor of a War Powers Resolution, this time calling the conflict “a Shakespearean tragedy on a global scale” in which “American lives have been lost” and “the world economy has been crippled.” In that statement, Hickenlooper said that “Coloradans are already facing a cost-of-living emergency,” adding, “We need lower costs for gas, groceries, housing, and health care. Not another endless conflict,” and concluding, “Congress never authorized this illegal war. Let’s obey the law and end it.”
By July, as ceasefire talks broke down and hostilities resumed, Hickenlooper again pressed the administration, saying at the time that “the whiplash from President Trump is just too much.” His office noted that he had by then “voted eight times to end Trump’s highly unpopular and illegal war with Iran,” pointing to rising gas prices and mounting costs for Colorado farmers as part of the toll of the ongoing fighting.
The renewed fighting has coincided with a sharp escalation in strikes on both sides. Iran’s Islamic Revolutionary Guard Corps has targeted shipping and infrastructure across the Gulf region in recent days, with Jordan’s Armed Forces stating it intercepted three Iranian missiles targeting its territory and Kuwaiti authorities reporting damage to oil-sector infrastructure and residential fires from falling debris. The U.S. State Department has issued a worldwide advisory telling Americans, particularly those in the Middle East, to “exercise increased caution” as the war continues. Iran’s Supreme Leader, Mojtaba Khamenei, said in a statement carried by state media that President Trump’s signature is “worthless and unreliable” following what he described as repeated U.S. violations of the memorandum of understanding between the two countries, adding that “bullying, hegemonic ambition, and brutality are inseparable elements of the American way.”
Defense Secretary Pete Hegseth addressed the American casualties directly following the Jordan attack, saying the loss of the U.S. soldiers “only stiffens our resolve,” a comment that underscored the administration’s continued commitment to the campaign even as congressional Democrats pressed for its end.
Hickenlooper’s Tuesday post placed particular emphasis on the financial toll of the war alongside its human cost, tying the “more than a hundred billion” dollars in military spending directly to domestic affordability pressures facing Colorado families. That framing has been a consistent thread in his public statements throughout the conflict, linking the war’s price tag to gas, grocery, and health care costs at home rather than treating the two as separate issues.
The Senate has now taken up multiple War Powers Resolutions attempting to force an end to U.S. military involvement in Iran without explicit congressional authorization, with Hickenlooper voting in favor each time. Each of the measures has failed, with the Senate’s April vote failing 50-48 largely along party lines, as most Senate Republicans continued to vote against the resolution.
As of Tuesday, the Trump administration had not issued a direct public response to Hickenlooper’s statement. CENTCOM’s most recent update indicated that strikes against Iranian targets were continuing, with no publicly announced timeline for a ceasefire or renewed negotiations between Washington and Tehran.
