Republicans in Congress have so far resisted public debate over the ongoing U.S. war with Iran, even as Senate Democrats demand hearings with Trump administration officials. Democrats are threatening to force a series of votes on the war in an effort to gum up the Senate's voting schedule and prod Republicans to action, but GOP lawmakers remain mostly resistant to the idea of quickly forcing public testimony before Congress.

Why it matters

The role of Congress in the deliberations over the Iran war is an unsettled question with enormous stakes, given that lawmakers have the power to shape the trajectory of the conflict as it grows in cost and casualties. So far, 13 military members have been killed and billions of dollars have been spent, but President Donald Trump has not sought congressional approval for attacking Iran.

The details

Republicans in Congress have side-stepped public debate over the war, even as Senate Democrats reach for every tool at their disposal to demand hearings with Trump administration officials. Increasingly frustrated, Democrats are threatening this week to force a series of votes on the war, hoping that the effort to gum up the Senate's voting schedule will prod Republicans to action.

  • The United States' war with Iran is entering its third week.
  • On Monday, the 17th day of the conflict dawned.

What they’re saying

“We've had no oversight whatsoever over what the executive is doing as we're spending a billion dollars a day, and we have failed to have any real substantive debate or discussion.”

— Cory Booker, Senator

“I don't want to just be given the invoice from the Department of Defense, saying this is what it's going to cost. I want them to be engaged with us.”

— Lisa Murkowski, Senator

“I think we have to let the objective play out as far as we can, and if then the effort gets murky on how to get to the objective, that might be a good time to have some hearings, but it's too early.”

— Cynthia Lummis, Senator

What’s next

The GOP chairs of committees dealing with national security have said they don't have plans in the near term to hold hearings specifically on the war, though some acknowledged the value of lawmaker questioning. An expected supplemental budget request from the Trump administration to cover the costs of the war is also likely weeks away and faces a difficult path through Congress.

The takeaway

The standoff between Republicans and Democrats over public hearings on the Iran war highlights the ongoing tensions over Congress' role in overseeing military conflicts initiated by the executive branch. As the war continues and costs mount, pressure is building for lawmakers to more actively scrutinize the administration's justifications and strategy.
