Rubio Confirms Iran Nuclear Talks as Senate Demands War Endgame

CNBC reported Tuesday that Secretary of State Marco Rubio told a Senate panel the U.S. is actively engaged in Iran nuclear talks. He said Tehran now appears willing to discuss elements of its nuclear program it had flatly refused to address until recently.

Talks Through Intermediaries

Rubio testified before the Senate Foreign Relations Committee, his first public appearance on the Iran conflict since U.S. and Israeli strikes began in late February. He told lawmakers that Iran nuclear talks proceed differently from standard diplomacy and rely on intermediaries rather than direct exchange. He said a breakthrough could come within days, though he stressed that any emerging framework would still need to meet standards acceptable to both Congress and the American public. The remarks marked a notable tonal shift from President Donald Trump’s comments just one day earlier, when Trump indicated he was indifferent to whether negotiations continued at all.

Background: Why the War Started

Rubio framed the original military campaign as a deliberate effort to dismantle what he described as Iran’s layered conventional defense network. He said Tehran had spent years assembling missiles, drones and naval forces specifically designed to deter any outside interference with its nuclear ambitions. That posture, he argued, amounted to a standing threat to overwhelm any adversary that challenged its program. The operation, which the administration has called “Epic Fury,” has significantly degraded Iran’s missile and drone production capacity, Rubio said, though he conceded drone manufacturing remains difficult to fully suppress given how cheaply and quickly the weapons can be built.

Hormuz Remains the Pressure Point

Reopening the Strait of Hormuz sits at the center of any de-escalation scenario, Rubio told the committee. He outlined a set of conditions Iran must meet, including formally declaring the waterway open to commercial shipping, halting toll collection on passing vessels, assisting in clearing naval mines and committing not to fire on merchant ships. The strait carries roughly one-fifth of global oil supply, making its status a live concern for energy markets and trading partners worldwide.

Congress Grows Uneasy

Democratic senators used the hearing to challenge the administration on both legal authority and strategic intent. Senator Jeanne Shaheen of New Hampshire, the panel’s ranking Democrat, accused the White House of circumventing congressional oversight rather than genuinely consulting lawmakers. She also pushed back on what she characterized as an undeclared agenda targeting governments in Cuba and Venezuela alongside Iran. Rubio is expected before additional House and Senate committees later this week as pressure for a defined war endgame intensifies on Capitol Hill.
