US Secretary of State Marco Rubio is set to face a litany of questions today about the Trump administration’s fragile or stalling diplomatic efforts around the world when he appears for back-to-back hearings on Capitol Hill for the first time since the Iran war began.

The former Republican senator will sit before House and Senate committees to make the State Department’s annual budget request. But the focus is likely to shift quickly to the already unsteady ceasefire between Washington and Tehran, which has been further tested in recent days by back-and-forth attacks.

Cabinet members, including Rubio, have defended President Donald Trump’s decision to launch the conflict despite promises over the years not to engage in “forever wars” in the Middle East. That work has been made more difficult by Trump’s shifting goals for the conflict.

While Rubio is testifying before Congress for the first time since the Iran war started on Feb. 28, he took part in a classified briefing for lawmakers days after the first US and Israeli strikes. He faced Democrats’ anger over the lack of congressional approval but strong support from most Republicans for taking action against one of America’s oldest adversaries.

In the two months since the war began, however, a small but growing faction of Republicans have joined Democrats in questioning the astronomical price tag and overall economic consequences of the conflict as they head into midterm elections in the fall.
