Ongoing U.S.-Iran negotiations following the June 2026 memorandum of understanding have produced no finalized nuclear agreement eligible for congressional review under the Iran Nuclear Agreement Review Act. Indirect talks through mediators continue amid disputes over uranium enrichment levels, sanctions relief, and the Strait of Hormuz, with the Trump administration rejecting recent Iranian proposals. Republican majorities in both chambers have passed symbolic war powers resolutions signaling concerns, while Democrats and some GOP members demand full INARA oversight and verifiable limits on Iran's nuclear program. Midterm elections in November further complicate legislative action before year-end, contributing to trader consensus that Congress is unlikely to approve any deal in 2026.
