Rubio Juggles State Department and National Security Roles Amid Iran Crisis

Marco Rubio has been carrying two of the government’s most demanding foreign-policy jobs at once, and the Iran crisis has made the split screen impossible to miss. As secretary of state and acting national security adviser, Rubio has spent nearly a year balancing diplomacy, war planning and public messaging while President Donald Trump leaned on aides and envoys to do much of the negotiating.

The arrangement has few modern parallels. Henry Kissinger is the last widely cited precedent for holding both posts at the same time, and even that benchmark only underscores how unusual Rubio’s workload has become. In March, Rubio described the U.S. operation against Iran as an effort to destroy Iran’s navy and air force and prevent Tehran from obtaining a nuclear weapon. He also helped shape the administration’s message around the campaign while taking on other assignments, including parts of Trump’s hemispheric strategy.

The State Department said on March 26 that 9,000 Americans had left the Middle East since the start of the war, with about 1,500 still asking for help getting out. Rubio’s portfolio has covered that evacuation effort as well as the larger military and diplomatic crisis, even as he has argued that the Pentagon should handle tactical military questions. The State Department said the United States was conducting an operation to eliminate the threat of Iran’s short-range ballistic missiles and the threat posed by its navy.

The bigger question has been who actually speaks for Washington. Rubio has remained one of the administration’s most visible foreign-policy voices, yet the Iran talks have often featured Vice President JD Vance and special envoy Steve Witkoff instead. On April 20, reports said Iran would not send negotiators to Islamabad for another round of talks, citing the U.S. blockade of Iranian ports. Trump still said he expected a deal relatively quickly. One day later, reports said Vance had planned to fly to Islamabad but stayed in Washington as the impasse continued.

Rubio has said backchannel communications with Iran were still moving through intermediaries, a sign that the administration’s diplomacy was continuing even as public negotiations stalled. The structure points to a White House in which Trump has outsourced much of the day-to-day diplomacy to aides, leaving Rubio to manage both the formal State Department and the national security system around the most volatile security file in the world.
