Secretary of State Marco Rubio told Congress on Tuesday that Iran has agreed to negotiate on aspects of its nuclear program that Tehran refused to discuss as recently as a year ago, a shift he cast as a sign of progress even as Democratic lawmakers hammered the administration's broader approach to the Middle East and beyond.
Rubio's testimony before the Senate Foreign Relations Committee and a House Appropriations subcommittee marked his first public appearance on Capitol Hill since the Iran conflict began at the end of February. Protesters briefly disrupted each session. And the hearings covered far more than Iran, touching on a shaky ceasefire, foreign aid, Pentagon strikes on alleged drug-smuggling vessels, and the dismantlement of the U.S. Agency for International Development.
But the central question, whether Washington can turn military pressure on Tehran into a workable nuclear agreement, drew the sharpest exchanges of the day.
Rubio framed the administration's posture as tough but open-handed. As Newsmax reported, the secretary told lawmakers:
"They have agreed to negotiate aspects of their nuclear program that just a month ago, just a year ago, they were refusing to even mention."
He stopped short of predicting an outcome. He would not offer an assessment of what talks might produce or guarantee that negotiations would lead to "a deal that's acceptable." That restraint is worth noting, it separates Rubio's posture from the Obama-era eagerness that produced the 2015 JCPOA, a deal conservatives rightly criticized for front-loading sanctions relief while leaving Iran's enrichment infrastructure largely intact.
On the Strait of Hormuz, the chokepoint through which a vast share of the world's oil passes, Rubio was blunt. Iran will not receive a "massive payout" simply for reopening the waterway. Any significant sanctions relief, he said, would require further concessions on the nuclear program.
"The more they give, the more they would get. They're not going to get it as a signing bonus."
That formulation matters. It signals the administration intends to hold leverage rather than trade it away up front, the opposite of the approach that defined the previous Democratic framework for dealing with Tehran.
The optimism, however, runs into a messy reality. Two semiofficial Iranian news agencies reported that Iran has stopped communicating with mediators after Israel threatened to bomb Beirut. President Trump disputed that account, calling the Iranian reports "false and erroneous."
Rubio also offered an intelligence-flavored observation about Iran's new supreme leader, Mojtaba Khamenei. He said there are indications Khamenei "is increasingly engaging at some level, although all of his communications have been in writing and through intermediaries." Khamenei has not been seen publicly since the conflict began, according to Rubio's testimony.
That detail raises as many questions as it answers. A leader communicating only through intermediaries and written messages could be consolidating control, or could be sidelined. Either way, it complicates any negotiation. The administration's willingness to acknowledge uncertainty here, rather than oversell the diplomatic picture, is a mark of seriousness.
The broader trajectory of U.S.-Iran tensions has been escalating for months. In May, Tehran warned of "renewed conflict" after Trump rejected its latest proposal, underscoring how fragile any diplomatic opening remains.
Democratic senators used the hearings to deliver broadsides against the administration. Sen. Chris Van Hollen of Maryland accused Trump of entering the conflict on behalf of Israel and invoked Israeli Prime Minister Benjamin Netanyahu.
"He said he's been waiting 40 years to do this. It turns out he finally found a president who was both s***** and reckless enough to join him. Let's face it, Mr. Secretary, the Trump foreign policy has become a dumpster fire."
Van Hollen's rhetoric was heated. What it lacked was a coherent counter-proposal. Democrats have spent months criticizing the administration's Iran posture without articulating what they would do differently beyond returning to the JCPOA framework, a deal that even many European allies acknowledged was insufficient to address Iran's ballistic missile program and regional aggression.
The hearing also touched on foreign aid. Rubio insisted that the dismantlement of USAID had not affected Washington's ability to respond to global humanitarian crises, including disease outbreaks such as Ebola in Africa. Democrats pushed back, but the secretary held his ground.
Rubio has been clear about his intentions at the State Department. He pledged last month to stay put at State and focus on the administration's foreign policy agenda, a signal that he views the current moment as consequential enough to warrant his full attention rather than early positioning for 2028.
The other flashpoint in Tuesday's hearings had nothing to do with Iran. Rubio faced questions about Pentagon strikes against dozens of alleged drug-smuggling vessels in the Caribbean Sea and eastern Pacific Ocean, operations that have killed more than 200 people since early September.
The Trump administration says the United States is at war with drug cartels, and it has used that framing to justify the maritime strikes. Rubio dismissed questions about their legality, telling lawmakers that every strike involves a legal officer who determines whether the action meets targeting criteria.
Sen. Tim Kaine of Virginia pushed back. He said the military's targeting criteria for the vessel strikes do not include drugs actually being present on the boat, a detail he called "odd." Kaine added that he could not share much more because the criteria are classified.
Rubio countered that the U.S. military has "walked away from strikes" multiple times when the criteria were not met, an assertion meant to demonstrate restraint and legal discipline in the operations. Whether that satisfies Congress remains to be seen. The legal authority underlying these strikes is an open question that neither Rubio nor Kaine fully resolved on Tuesday.
The Strait of Hormuz itself has been a theater of direct military action. Late last month, the U.S. military destroyed Iranian mine-laying boats and a missile site in the waterway, a reminder that the diplomatic track Rubio described operates against a backdrop of active hostilities.
While Rubio testified, Israel and Lebanon began a new round of political talks at the State Department, a parallel track that underscores how many moving pieces the administration is managing simultaneously. The ceasefire between Israel and Hezbollah, described as increasingly in doubt, adds another layer of instability.
The internal debates that preceded the current Iran posture have been extensive. Reporting earlier this spring detailed the Israeli pitch that preceded Operation Epic Fury and the Trump advisers who pushed back, illustrating the range of views within the administration about how far to go.
Rubio faces additional hearings Wednesday on the State Department's annual budget request. Those sessions will likely revisit many of the same themes, USAID, Iran, and the legal framework for military operations abroad.
The administration's willingness to engage diplomatically with Iran while maintaining maximum pressure is the right instinct. But Rubio himself acknowledged there is no guarantee of success. The question is whether this administration can hold its leverage long enough to force real concessions, or whether the fog of a multi-front conflict, congressional skepticism, and Tehran's own calculations will overtake the effort.
Rubio's handling of foreign aid questions also reflects the administration's broader restructuring philosophy. His insistence that USAID's dismantlement has not degraded humanitarian response capacity echoes the same argument he made when Cuba's communist regime turned down $100 million in U.S. humanitarian aid, that the problem is not American generosity but the regimes that refuse it or exploit it.
Democrats can call the administration's foreign policy a "dumpster fire" all they want. But the party that handed Iran pallets of cash and called it diplomacy has yet to explain what it would do differently now, besides complain.
