Secretary of State Marco Rubio testified before a House Appropriations subcommittee and the Senate Foreign Relations Committee on Tuesday, marking his first public congressional appearance since the Iran war began at the end of February. The hearings came as the ceasefire between Israel and Iran appeared increasingly fragile.
Rubio told senators that Iranians have agreed to negotiate aspects of their nuclear program that they had been refusing to address just months ago. However, he said there was no guarantee those negotiations would produce an acceptable deal. "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," Rubio said.
The Secretary of State's optimism ran counter to reports from two semiofficial Iranian news agencies indicating Iran had stopped communicating with mediators after Israel threatened to bomb Beirut amid its conflict with the Hezbollah militant group. President Donald Trump disputed those reports, calling them "false and erroneous."
Rubio also addressed the potential for sanctions relief tied to reopening the Strait of Hormuz, a crucial waterway for global oil shipments. He said Iran would need to make further concessions on its nuclear program to receive significant sanctions relief rather than receiving it as an initial incentive. "The more they give, the more they would get," he said.
What the Right Is Saying
Rubio defended the Trump administration's approach to Iran and other global hotspots during his testimony. He maintained that negotiations with Tehran remain possible despite the instability in Iran's leadership following the conflict.
"I really don't believe this system is capable of reform unless new people take over or a new mindset takes hold," Rubio said when asked about Cuba, which Trump has hinted could be the next U.S. target after operations in Iran conclude.
Rubio pushed back against Democratic concerns about the legality of drug cartel strikes, saying every strike includes a legal officer who determines whether it meets legal requirements. "The U.S. military has walked away from strikes multiple times because they did not meet the targeting criteria," he said.
On Taiwan arms sales, Rubio acknowledged that a potential $14 billion sale remains under consideration and would not be canceled despite Chinese objections. He said timing of the sale is something "the president will have to decide."
What the Left Is Saying
Democratic lawmakers criticized the Trump administration's handling of Iran and broader foreign policy during Rubio's testimony. Sen. Chris Van Hollen, D-Md., specifically took aim at the U.S. and Israeli decision to strike Iran, accusing President Trump of entering the conflict on behalf of Israel.
"Israeli Prime Minister Benjamin Netanyahu said he's been waiting 40 years to do this," Van Hollen said. "It turns out he finally found a president who was both stupid and reckless enough to join him. Let's face it, Mr. Secretary, the Trump foreign policy has become a dumpster fire."
Senators also pressed Rubio on cuts to U.S. foreign aid and concerns about responding to global health crises such as the Ebola outbreak in Africa. Van Hollen blasted Rubio and the administration for foreign aid reductions and overseas intervention policies.
Democratic Sen. Tim Kaine of Virginia questioned the legality of Pentagon strikes against alleged drug-smuggling vessels in the Caribbean Sea and eastern Pacific Ocean, which have killed more than 200 people since September. Kaine noted that drugs being on boats was not among the military's targeting criteria for those strikes.
What the Numbers Show
Rubio testified at two separate hearings Tuesday — before the Senate Foreign Relations Committee at 10 a.m. EDT and the House Appropriations subcommittee at 2 p.m. EDT.
Pentagon strikes against alleged drug-smuggling vessels have killed more than 200 people since early September, according to military reports cited during the hearing.
The potential Taiwan arms sale Rubio discussed totals $14 billion. The U.S. recently completed an $11 billion arms sale to Taiwan in December 2025.
Rubio noted that Iran's new supreme leader, Mojtaba Khamenei, appears increasingly engaged in nuclear discussions despite not being seen publicly since the Iran war began at the end of February.
The Bottom Line
Rubio's testimony marked the first public congressional appearance by a senior Trump administration official since the Iran conflict began. His optimistic framing on nuclear negotiations was quickly challenged by Democratic lawmakers who questioned the administration's broader foreign policy approach.
The competing narratives — Rubio's stated optimism about talks versus Iranian reports of halted communications with mediators — highlight the uncertainty surrounding efforts to resolve the conflict. The status of the ceasefire and whether meaningful negotiations can resume remain open questions.
Rubio also faced questions on unrelated issues including drug cartel strikes, Cuba policy, and foreign aid cuts during his testimony, reflecting the breadth of concerns Congress has regarding the administration's global posture.
