Congress is the legislative branch, not in charge of the armed forces or foreign policy, which is the purview of the executive branch. They can certainly cut the budget, as they hold the purse strings, but they are not empowered to assault the arrangements as written down in the Constitution.

Yup, they're trying to micro-manange the war. This anti-constitutional power grab is a non-starter. Go ahead try to cut off funds, leave our tropps vulnerable. These anti-War Dems are driving their party of the cliff.
