Senate Republicans face internal divisions and timing pressures that complicate passage of a third reconciliation package before the November 2026 midterms. Following the June 2026 enactment of the $70 billion immigration enforcement bill—the second reconciliation measure of the Congress—House leaders advanced a budget resolution outlining roughly $95 billion in defense, farm, and election security provisions. Senate Majority Leader John Thune has delayed action on the resolution, citing insufficient support, a preference for completing appropriations negotiations first, and reluctance to expose members to contentious amendment votes during a vote-a-rama. President Trump and Senate Budget Chair Ron Johnson continue pressing for progress when the chamber returns in September, but differing GOP priorities on spending offsets and policy riders remain key obstacles.
