Congressional Democrats are intensifying pressure for public hearings on the United States' military conflict with Iran, now in its third week, while Republicans resist calls for immediate oversight of the Trump administration's conduct of the war.

Six Democratic senators have threatened to force daily votes on war powers resolutions unless hearings are scheduled with Defense Secretary Pete Hegseth, Secretary of State Marco Rubio, and other Cabinet officials. The procedural tactic would consume valuable Senate floor time and potentially disrupt Republican legislative priorities, including voting legislation with strict proof-of-citizenship requirements.

"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," said Sen. Cory Booker, D-N.J. The conflict has resulted in 13 military deaths and billions in spending, with President Trump not seeking congressional approval for the attacks.

Senate Majority Leader John Thune, R-S.D., said he does not expect public hearings specifically on the Iran war, pointing to classified briefings and regular news conferences by defense officials. "They have briefed us," Thune said, noting that military policy discussions would occur during routine testimony on defense spending and policy.

Some Republicans are showing signs of frustration with the administration's approach. Sen. Lisa Murkowski, R-Alaska, said she wants engagement beyond "just being given the invoice from the Department of Defense." Sen. John Kennedy, R-La., called a recent classified briefing a "total waste of time" due to officials' inability to provide adequate answers.

Trump has shifted objectives for the conflict, ranging from crippling Iran's military capabilities to demanding "unconditional surrender." Republicans have largely supported the decision to attack Iran but express wariness about a prolonged conflict as midterm elections approach and public support remains limited.
