Defense Secretary Pete Hegseth and Chairman of the Joint Chiefs of Staff Dan Caine are scheduled to appear before the House Armed Services Committee on Wednesday.
This marks the first time since the war with Iran began two months ago that the defense chief will face direct questioning from lawmakers.
The session is expected to focus heavily on the Pentagon's budget for the coming year and how military resources are being allocated amid the ongoing conflict.
The hearing comes at a critical juncture as the war with Iran continues to dominate political and military discussions.
Lawmakers are anticipated to press both officials on the strategic implications of the conflict, the financial burden it places on the defense budget, and the readiness of U.S. forces in the region.
The session will also likely touch on broader defense priorities and how the war is shaping military planning and resource allocation.
