The debt limit is, in strict operational terms, a fiction. Congress authorizes spending through the appropriations process. It authorizes revenue through the tax code. The debt that results from the gap between those two is mathematically determined. The debt limit then arrives as a third act — a separate legislative mechanism that can block Treasury from issuing the securities needed to pay obligations Congress has already created. It does not constrain spending.

The tone coming out of Washington is shifting, and not in a subtle way. A group of Democratic members on the House Armed Services Committee, led by Congressman John Garamendi, is openly pressing for immediate public testimony from the Department of Defense regarding the ongoing U.S. military actions tied to Iran. The request, directed to committee chairman Mike Rogers, signals growing unease not just about the conflict itself, but about how little clarity Congress feels it has over its scope, objectives, and trajectory.
