Rubio to testify before Congress on Iran war

US Secretary of State Marco Rubio is set to testify in back-to-back hearings on Capitol Hill in Washington on Tuesday, June 2, 2026.

Lawmakers are expected to press him on the Trump administration’s diplomacy as the Iran war continues, making the hearings a test of US foreign policy under widening pressure.

Trump administration

The administration is presenting Rubio’s testimony as part of routine oversight while it faces questions about diplomacy in several regions. It is likely to stress that negotiations and pressure remain tools available to the United States.

Congress

Members of Congress are expected to use the hearings to demand answers on the Iran war and other stalled diplomatic efforts. They are likely to focus on whether the administration has a clear strategy and what risks it sees ahead.

  • Capitol Hill takes its name from the dome-topped building that houses Congress.
  • The US secretary of state is usually the president’s top diplomat.
  • Congressional hearings are often televised and can quickly become major political events.

US-Iran Ceasefire War

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
